1 edit | P4 HT or Core 2? Looking to get a bit more performance without spending 2K.
At the moment I have a P-4 2.8 GHz W/Hyper-threading socket 775 800Mhz FSB and 4 Gb DDR2. The board will support a 3.0 GHz core2 duo 1066 FSB and 3Mbs L2
With my astro photography I can be working with 20+ 25Mb images at a time. Would the Core 2 Duo processor make a noticeable difference in performance?
(EDIT)-- to add the Hyper-Threading

Greenwich, CT | Core 2 Duo for sure as far as the specs and nitty gritty I will leave that for others to tell but I'm pretty sure the C2D is much faster in overall speed then a P4 with H/T however I know photoshop makes uses of the extra cores of the C2D |

There's some good stuff in this old thread, where I asked a similar question a while back:
»Fast P4 or slow Core 2 Duo? Which is better for games? |

If you are sure your motherboard supports core 2 then I would say yes it would be worth doing especially if you are doing batch file manipulation on the images.
What is your main complaint with your system when handling images? |

Thanks HarryH3 Good read and info.

According to Intels site it does support Core2Duo.
Intel D946GZIS Motherboard.

The main problem is speed of processing the images. What I need to do is stack multiple images. As stated I can load sometimes over 20 25+Mb images into a program. The program detects the number of stars in the "light" images then creates a "master dark frame" from the loaded "dark images and then does a dark subtract of each image from the "master dark" file to help reduce noise. It then adjusts the field from the "flat field" images loaded to help reduce uneven illumination which causes gradients. Then it will align and stack all the corrected light images to create one final image. Then I need to do some final adjustments in Photoshop of the single stacked image.
All those steps take time and power and I would just like to make the time a bit less by adding some processing power. But only if it may make a noticeable difference.

Then I would say moving to a core2 duo would be a good idea.
I'm interested in hearing your opinion of the results if you do this. |

how much do you want to spend
you can get an i5 for 400 or so
a Core 2 will eat the P4 alive in ever benchmark you could run
and the i5 will just curbstomp them both
but depending on the motherboard you have you may just want to replace it any way
another good option is a Q9400 cheap quad core and still stomp the P4 but youll need a new mobo |

These days it's pretty hard to get an equitable upgrade done in a relatively reasonable fashion cost wise. This is one time from what you have provided were it's cost effective to change out just the CPU.
As a point of interest my Rig is heavily reworked with a core 2 and from the desktop to actually beginning work on the older Photoshop 6 takes 4 seconds, prior to the core 2 it took about that many minutes. It's a worthy upgrade.

Simple answer: Core 2 Duo.
Avoid the P4 in question. Hyperthreading doesn't get you jack squat (really! Especially on the P4s), while the C2D gets you two physical processors.
Yes, a C2D will make a noticeable difference when it comes to your work, assuming the software you're using is threaded.
C2D will also draw less power overall.  If you can afford it, consider a C2Q or a C2D with larger cache.

Thanhs for all the feedback everone. The mobo I have now is fairly new. My old one went out a few months after upgrading the memory so I bought a board compatible wit the hardware I had. I now upgraded the memory ( speed and amount) as the new board supports more than the last one did. I don't want to replace everything but do want to gain some speed. It looks like the processor will make a difference so I will upgrade it. The board only supports up to 1066 FSB so I will get the fastest highest L2 I can.
Thanks again all.

That's a reasonable conclusion, for your issue. Hope it goes well, really. If not post back. |

here's the list of compatible newer CPUs: »processormatch.intel.com/CompDB/···d946gzis
fastest is e6700. you can't really find new e6700's/Core2Duos these days. i think all of them have been EOL'ed in favor of cheaper C2Quads. your best bet is either ebay or for sale forums for used ones.
that board is definitely NOT new. it may be new to you, but it's an older chipset and an older board.
you would be better off getting a Core i5 system for $400, plus RAM. 4GB is around $90, so about 500 for a system that blows almost anything out of the water is a great buy right now.

| The board was new and I knew it was basically obsolete when I bought it.
Well now, from the looks of your link the processor I was thinking of getting may not work.
»www.newegg.com/Product/ProductLi···=1066MHz
Even though the spec sheet said
" Intel® Core™2 Duo processor in an LGA775 socket with a 1066 or 800 MHz
system bus" It doesn't mean all 1066 775 processors. That throws a wrench into the works. I didn't want to drop that kind of money into the computer because I need a new telescope before a computer.
You need to change your name to BUZZKILLSomnambul33t 
only kidding of course thanks for the info.

check ebay for new/used e6000 C2Ds. just make sure it comes with a heatsink fan unless you have a good one you can use.
you can never trust those lists of supported CPUs unless it's directly on the MFG's website. most of those "all C2Ds 1066 FSB" lines are created when the mobo is new. after new revisions and models of CPUs come out, it's often not correct anymore.
also, Intel is the best MFG for lists of supported CPUs for their mobos because of that link i showed you. one exists for every motherboard they made
