I have been shopping lately for a new computer and am so for getting more confused. I want a Quad core but what is the difference between an I5 and an I7 price and performance-wise The machine will be used for surfing, E-mail, Collage and high-school homework by the grandkids and will run Folding at home to find a cure for various diseases. Only kids games will be played on it.

asdfdfdfdfdf @Level3.net	For what you are using the system for there is no significant difference. All else being equal I would choose on price. Kids games can probably get by with integrated graphics. If you have links to what you are looking at we will have a look and see if there are other issues involved.

Diablo II got by on the integrated graphics of our older PC's, WoW required a semi-respectable graphics card. If your kids are high school or college age, they may be playing WoW or other high end PC games and may require at least a decent graphics card.

rfhar The World Sport, Played In Every Country Premium join:2001-03-26 Buicktown,Mi clubs: ·Power-Net Internet..	reply to rfhar Thanks for the input folks. I went to a computer store today and luck walked in with me. The gal I talked to has been building computers for four years now and could answer questions far better than any normal salesperson. The I5 is a quad core machine and the I7 has a hyperthreaded quad core. She told me that it is a lot faster too. Now after I absorb all she told I will likely have more queries. -- Whoever said that ignorance is bliss wasn't refering to a person with a computer at his fingertips! Cure Disease with your computer

asdfdfdfdfdf @Level3.net	It is true the i7 is hyperthreaded and the i5 isn't. It is NOT true that the i7 is a lot faster. Especially for the uses you describe it isn't going to matter much so don't pay a premium for the i7. The advantage of the i5 is that you get i7 level performance but can do it at lower cost but it will depend on motherboard choice. If a company insists on matching an i5 with an expensive motherboard then they are defeating the advantage of the i5. Just keep in mind that the salespeople, even if they aren't working on commission, may be pressured to push certain merchandise. We don't have any financial incentive so if you want to run things by us please do so. Looking at your profile I see you bought your last system from a local business called ekos computers. It sounds like you may be doing this again. I'm guessing you want to support local businesses but there isn't much reason to pay a premium for a custom built system, based on the uses you describe. If you have some concern about not spending unnecessary money you can give us an idea of what kinds of specs they are trying to sell you on and the relative prices of the i5 and i7 systems they are discussing so we can give you better advice. It is difficult to give good help based solely on general discussions about i5 and i7. I'm wondering what caused you to focus on these chips anyway. Was it something you chose on your own or is it something that the store was pushing you toward?

asdfdfdfdfdf @Level3.net	reply to rfhar Let me clarify my previous post because I don't mean to poison your attitude toward ekos or suggest they are behaving in some questionable way. It is difficult for a small builder operation to thrive in today's market. It's just that we are here to look out for the person posting and the interests of a small volume local business may not always coincide with your interests. A lot of it comes down to the flexibility of your budget.

I will have a one year warranty. This means that I try to find a sweet spot between expense and what be up to date the longest. They are recommending a Intel DP55WG LG1156 at $169. and a Intel Core i7-860 at $369. They do sell a i5-750 for $259.

asdfdfdfdfdf @Level3.net	reply to rfhar "I will be running Folding at home on tis computer so do want a little speed." It is important to understand that hyperthreading isn't like having twice the number of cores. It enhances efficient use of the core under certain circumstances but it isn't going to do anything like what one might assume based on the doubling of reported cores in the operating system. You still only have 4 cores. In fact, although there is a lot of debate about this, the official pande group stance is still that enabling hyperthreading slows the return of work units and therefore is discouraged as the science wants units returned as quickly as possible. With HT enabled more units are worked on but frame times increase significantly so each work unit takes longer. It used to be that disabling hyperthreading was suggested. The faq still suggests disabling hyperthreading on quad cores. You are used to running on a p4. With a multicore system it isn't a simple matter of just installing your previous folding client. There are a number of options including running multiple(4) instances of the single core client or running one of the smp clients. We can discuss this in more depth. If you are really wanting to max your benefit to folding it might make more sense to get the i5 and put the money saved into a graphics card that can run the gpu client. This may all be very bewildering. If you feel overwhelmed and would prefer I cease discussing the complexities of this I will do so because I'm not trying to make things unnecessarily complicated. The long and short of it is that I just think the benefit of the i7 is being overrated, including for folding. You will have to look into the details of running folding@home on your new system though because it will become more complicated whatever you choose. Here is a good link which organizes some of the complications: »www.overclock.net/overclock-net-···ome.html

rfhar The World Sport, Played In Every Country Premium join:2001-03-26 Buicktown,Mi clubs: ·Power-Net Internet..	reply to rfhar I realy appreciate the input from you as I am in the learning mode presently. I liked the i7 as I have a P4-2600 HT computer now and even though it is getting old it still sends the WU's back within the deadline. The sales gal is suggesting a PNY nVidia GeForce 9600GT PCI-E 1GB video card. I have very little knowledge of what Cards folding at home needs to run the gpu client. I do not even understand Aero but want to have it I think. I'm still looking for a person who knows what Aero is presently just have not asked the right people yet. I will be into the link you provided tomorrow morning. Thanks a bunch. -- Whoever said that ignorance is bliss wasn't refering to a person with a computer at his fingertips!

AMDGamer join:2003-10-15 Warren, MI	reply to rfhar Just an FYI, I understand you like supporting local business's, but there is a MicroCenter nearby your in Madison Heights, where you can get the i5 750 for $159.99 and the i7 860 for $229.99. Also, they have motherboards for those 2 CPU's starting at $99.99, not to mention, the BYOS employees there are VERY knowledgeable. BTW I agree with asdf, i7 is overkill for you, stick with the i5. --

srr2 join:2001-12-20 Bethlehem, PA ·RCN CABLE 1 edit	reply to rfhar If you don't mind a contrarian opinion -- IMO, you're excessively concerned with this distributed computing business. You're proposing to spend an extra $50 to $100 on a video card you don't need, and possibly even more on processor capacity similarly in excess. Then there's the matter of the electricity that you're going to burn by loading up something like a quad processor during periods where it would be otherwise in a greatly-reduced power state. That electricity is not inconsequential and not free. Taking my Q9550 system as an example, the difference between idle and all cores at 100% is nearly 60W. Do you have any idea what 60W is going to cost you? Let's see.... 60W @ 24/7 for a year = 526KWH in a year. I don't know what electric rates are in MI, but let's assume about $0.13/KWH, so that electricity is costing you slightly more than $68/year. You're looking at spending maybe $100 or more non-recurring and nearly $70/year recurring expense. You would be doing them a much greater favor sending them a check! They could use the money directly to buy some supercomputer time that's 1000X more cost-effective (flops/$ I mean) than wasting resources on these so-called "free" small-computer clock cycles. Distributed computing might have made some sense during the early days of the P4, but with the developments in power-reducing technology, it no longer does. Those "free" clock cycles now have real consequences, real costs, and real WASTE associated with them, regardless of the social nobility of the project. Send the organization a check. Really. They'll get FAR more from the money directly. Make your life easier by buying a nice ready-to-go Dell system that will sit there quietly, consuming only 30-40W while you're not using it. On edit: Come to think of it, when you're not using it, put it on standby and send them a check for $120/year.

asdfdfdfdfdf @Level3.net	reply to rfhar " I am wondering if I may be overspending for what I want." I think this is likely true. In general the needs you describe are quite modest and do not require a powerful machine. There are some areas that need to be focused down or you will continue to feel overwhelmed by options. I think it would be helpful to take a more structured approach and narrow down some specifics. 1. What software is involved in collage. I'm not familiar with this so understanding the specific software is important. I will do some research on any software I'm not familiar with to determine requirements. 2. Let's narrow down how you want to run folding@home. Do you intend to crunch for folding 24 hours a day or to run it when the machine is normally on and in use and shut the machine down when it would otherwise be idle? This is a key decision. You need to keep in mind the considerable electrical use involved with constant crunching, as srr2 points out. In fact the numbers would be considerably higher if we were discussing gpu folding on top of the cpu clients. We can discuss this more if you wish. If you want to crunch constantly than that will have to be a key requirement that we design the system around. If you want to crunch when the system would normally be on and turn it off when it would otherwise be idle then it would make sense to design the system around your other needs and let this fall out where it will(which will be considerably better than your present system under any circumstances). My person feeling is that the latter would be more appropriate for you. I understand you want to do whatever you can for a good cause but I don't sense that you want this to be a consuming passion like it is with some techies. At any rate, nailing this issue down is key. 3.Give us an idea of the budget range that is acceptable to you, from a "would prefer" number to a maximum. 4. Can you tell us what kind of system prices were being suggested to you for the i5 setup you described above? This will give us a point of comparison with the digilink options. I have looked at the digilink links and list you gave. If this is the place you want to buy from then I will focus on those options. I have some preliminary thoughts but there is no point in my going into them at the moment. Lets get the details down on the above questions and then we'll be in a position to move forward with some sound starting recommendations and you won't have to feel like you're floundering.

It's not quite the same but i've been able to have some of the guys I work with benchmark our Xeon 55xx systems with their number crunching software (the 55xx is equivalent to the i7s). What we found is that running with hyperthreading on, with four threads, is faster than without hyperthreading. What we also found was, a task that would take 5 minutes with four threads (hyperthreaded), would take 8 minutes with eight threads. So, for an extra three minutes, you can crunch twice the amount of data. Or at least, that's what my number crunching guy told me. Granted it may not always scale like that, but using all logical cores is workable.

asdfdfdfdfdf @Level3.net	reply to rfhar Ok. Taking into account that the budget seems to be pretty large. You want to run folding@home 24/7. Other uses are very modest. You want a fairly high end system. $1600-$1700 for a core i5/i7 is really excessive for your situation. Looking at digilink my suggestion would be to focus on the xd-64 quad systems, either the intel Q8400 or the amd phenom II 945. My preference would be the phenom II but either is ok. The standard configuration is mostly ok. A 9600gt card would give quite decent gpu folding performance for the money. You could also consider the 9800gt, which may not cost much more, would perform better for folding but would also draw 40-50 watts more power. The one change I would want to make is to bump up the ram to 4GB, rather than 2GB. They are very stingy with the ram in all their standard configurations. I also don't think you need windows 7 ultimate. I think saving $100 and going with home premium would be fine. »www.intowindows.com/difference-b···ditions/ »windows.microsoft.com/en-US/wind···/compare This would be a good balance between cost and folding performance. I will discuss anything in more detail if you wish. I don't know how much flexibility they give you with a build.
