Is i7 920/930 a waste of money compared to an i5 750 ?

There seems to be an even split in some forums on which CPU or even chipset: X58 vs P55 in terms of future proofing and getting the best bang for your buck.

Personally, I was thinking of going with an i7 920 or 930 for due to it's ability to perform very well when performing video rendering. I plan to keep my new build for at least 2-3 years without upgrading anything but maybe RAM and adding more HDs, likely in the form of SSD drives. I'm not into overclocking but I would like to get a mobo that can handle SATA 6 Gbps without any restriction on the PCIe 2x slot. Something that at all Gigabyte mobos have at this time.

I am not into gaming so I don't plan on spending a lot of money on a video card and I won't likely be utilizing 2 PCIe 2x slots for Xfire or SLI use. However, if there are new peripherals that would require the use of a PCIe x2 slot, I would likely use the extra slot(s).

What's everyone's opinion on this subject?

depends
imo if you want a great chip but dont want or need SLi Crossfire
the i7 860 is great if you want a full i7 with HT if you dont think you need HT i5 750 is an amazing CPU for the money
comes down to what you need
do you NEED Crossfire or SLi?
do you NEED Hyperthreading?
do you NEED 6GB of ram?

i was no,yes and no so i got the i7 860

I do some of this on my 920, xvid-multicore single-pass (q4) encodes in virtualdub, average 70fps on 960x600 (fraps half-res recordings) with all eight logical cores doing something.

You are referring to the fact that the gigabyte 1156 boards take pci-e lanes from the graphics card to support sata 6 and usb 3.

Since you aren't gaming this isn't an issue for you. Running one low end graphics card x8 isn't going to be a problem in any way.
I don't think there are going to be non-graphics cards that will need a second x16 slot, especially in the next few years.
Keep in mind intel chipsets aren't going to be supporting these things until 2011. In 2-3 years you aren't going to be running into problems with either choice.

I was referring here to the platform choice and your concerns about sata 6 /usb 3 on 1156.

Whether you want to spend for a 920 or 860(hyperthreading) vs. the 750 is a different question. It would be best to analyze this question looking at specific benchmarks for the video application you are using, if available.

I have both a Core i7 920 and a Core i7 860. Personally I don’t notice mush difference between the two but the Core i7 860 did seem a hair faster when I first built it. The Core i7 920 was already about a year old by that point though so its not really a fair comparison to contrast a fresh build / OS install.

I don’t think there will be much difference between the Core i7 920 and 930. The Core i5 750 is also a fast part so I think you’re looking at four horses that are in a close race.

For the average user, in a blind taste test, I don’t think they would see much difference.

future proofing isn’t really clear to me either way. Sandy Bridge may or may not wean users off of the current platforms but Gulftown will likely be costly.

I just bought an i7-860. The Asus p7p55d-e pro has a PCIe bridge chip such that the SATA3 and USB3 don't take away from the PCIe 2.0 graphics lanes. What it does is take 4 PCIe 1.0-speed (2.5gbps) from the P55 and bridge them to two 5gbps lanes, one each for USB3 and SATA3.

This page has the clearest representation of what's going even though it is in Russian(?). The linked page is what happens on the Gigabyte boards where the USB3 and SATA3 either steal from the graphics lanes or run slower on P55 PCIe 1.0 lanes. Going to the next page to see "ASUS' oplossing", the PLX chip bridges 4 1.0 lanes into 2 2.0 lanes without affecting the graphics interface.

Unfortunately, I can't find any specific benchmarks. However, some users subjectively reported seeing upto a 50% increase in speeds using a i7 920 over the i5 750 with video rendering.

And I think u nailed it on the head. Do I really want to spend the difference on an i7 930 which is about the same price as the i7 860 P55 platform which according to some reviews, the P55 wasn't really designed for SATA 6 or USB 3, with the exception of Asus boards using a bridge, but it still has some bottlenecks as posted by pnjunction.

Still, I am confused on not sure which way to go. Perhaps I should wait even longer to see what AMD will come up with?

Wow. Woa. WTF. Gee whiz! Dag! Are they from China like so many counterfeits? I hope someone pays big time for this wherever they came from! If they were really fabbed it would be good to close down the fab and sell off the equipment so it doesn't happen again!

...Or, were they non functioning? This is going to hurt newegg.

I heard about the counterfeit CPUS. I wonder how they perform and how much cheaper are they compared to the real thing?

Definitely not functioning, they would be impossible to reproduce. LOL at 'close down the fab' they cost billions of dollars no way some counterfeiter built one. They replicated the appearance only.

Don't see how this hurts newegg so badly, they shipped some 'defective' units that they will replace I'm sure. It would take a 'special' kind of customer to avoid newegg because of a small issue like this that I'm sure they will fix.

But will they replace the mainboards these things fried too?

I know that they couldn't reproduce a genuine, or anything close to it, but I was wondering if these were test chips that escaped the field. Or, a truck shipment that was hijacked by gangs. I remember when working in San Jose hearing about such things, it actually made me nervous because I worked in the industry and I didn't want to get jumped or something.

I imagine Intel uses armored transport or something now?

They probably would but damn how dumb would you have to be to put that in a mobo and power it up?

Did you look at the bottom? They only replicated the top the bottom doesn't even have metal pins on it.

Not to mention you'd have a tough time installing that cooling fan... (or you'd be colossally stupid to ignore the foam fan and install the fake cpu with a 3rd part cooler).

I doubt Intel (or any electronics company whose truckload of goods would have similar value) worries that much about security. Those kind of hijackings are harder to get away with these days. Most likely this swap was an inside job.

It's nothing like that. The "chip" is simply a piece of cardboard with a nice looking heatspreader on top.

Those who have worked for large hardware retailers or distributors probably aren't surprised. This kind of thing isn't unheard of. Generally, the skimmers will cut simply cut the processor out of the box using an X-Acto knife. Retailers order a few hundred to a thousand processors. There's no way to check until it's too late. Obviously, this swap doesn't occur during production, but somewhere downstream after the processors reach the distributors or are being sent to retailers.

Oh, I didn't see that, them not having pins. So it wasn't even a real attempt at anything. Not even some rudimentry fab with circuitry to hide how fake. Something that fake should not have taken so long to catch. Newegg must have been asleep at the wheel. Or maybe they didn't believe the first 200 complaints? Man I'd hate to get stuck with something as tight as money is!

No point in making any circuitry unless you go all the way since they won't work anyways.

Newegg is a huge operation and the 920 is popular product, they could easily have shipped all 300 before the first one arrived to a customer.

So they could actually ship 300 or more in a day? Woa! The founders of newegg must be loaded.

They have millions of customers nation-wide and only a few major distribution centers.

I saw a video on their operation and how automated and secure it is. The automation might have burned them a bit here, although having a person take a hard enough look at each and every box to spot fakes like this would take an insane amount of resources.

300 bad chips at roughly ~$300 a pop equates to about ~$90,000 USD. Not a small sum to lose, not a small some at all.

Now I know how Microscenter sells their Core i7 920 chips so cheap,…they must have fallen off the back of a truck and landed in their warehouse

Seriously though I don’t think there is much for us to worry about but actually going into a store and buying a chip there would help weed out this extremely unlikely event. If you have a Microcenter nearby you can certainly save a lot on any one of the four above chips.
