Default Upgrading Core2Quad to Corei7, running gtx 275 SLI

Hello everyone,

I'm considering to upgrade from Q6600 OC-ed to 3.6 ghz on a 680i sli to Corei7 on X58, and I intend to keep two gtx 275's SLI-ed for the time being.
Does anybody have any idea if I will gain some additional FPS (especialy in Crysis) changing from 3.6 ghz Q6600 to Core i7 running between 3.6 - 4 ghz , which is what most people get on air cooling. That is on gtx 275 SLI.

Thanks

I think you will, especially at higher resolutions. With the one I have, I ran really smooth all the way through at 1680x1050, everything maxed out with some AA.

You will gain FPS (mileage will vary depending on the game, some games are more CPU-dependent than others), but if you already were getting solid framerates with your old system, will you really notice the FPS increase? Since your video cards are the same, running in heavily GPU stressing conditions (high amounts of anti-aliasing, very high resolutions) won't really be affected by the CPU upgrade.

If you are upgrading for other reasons as well (faster video encoding, triple channel memory, future upgrade possibilities e.g. Core i9), I would say by all means go for it, but to upgrade from what you have for pure gaming purposes might be a bit more iffy.

Thank you for your reply people.
I realize now that I forgot to mention that I'm gaming at 1680x1050, usually with 4xAA and 16xAF.
I agree that there is a lot of advantages with X58 platform that could come in very usefull in the future, but this review: http://www.tomshardware.com/reviews/...ng,2061-8.html made me think that I could gain some frames by going to X58 platform right now.
Just look at the difference between Corei7 and Core2Quad clocked at 3.2 ghz with gtx 285 SLI. It is 34 vs. 22 at 1920x1200 with 8xAA ( if this review is to be believed)

Go for it. I think WINDOWS 7 would benefit with more threads.

Thanks mate. I will probably go for it, I'm now thinking what motherboard to buy with Corei7 920.

Obviously some naysayers will cast a jaundiced eye towards such an upgrade. I mean afterall, you're already running a quad and it's overclocked to a decent degree.

What you gain is triple channel RAM, onboard memory controller (and compared to the older version FSB it really is much quicker) and, if nothing else, what appears to be a good upgrade path to i9 in the future.

For me, I went from a c2d E6700 @ 3.2 to an i7 @ 3.8 and the difference is night and day...as it should be.

Possibility to upgrade to Core i9 sometime in the future is the main reason i would go for x58 and not p55 motherboard.
Just recently I ran across couple of reviews comparing Core i7 to Core2Quad on multi gpu platforms and came to a conclusion that I could gain some additional FPS right now by changing my platform to x58,Core i7 combo, plus I would be ready for future CPU upgrade.
I would really appreciate if someone that recently went from Core2Quad to Core i7 and runs some serious SLI setup at the same time, would share his experience.

Thanks

With a single card the upgrade is questionable but sli wants it.

That's how it is ,Do it.

That is what I upgrade from a Q6600 3.5gigs and a EVGa 680i SLI to a i7 920 running at 4.2gigs and a gigabyte EX58 UD5 and I seen a increase in all my games could have been from the extra speed of the processor ,but all in all I am very happy with the upgrade.

Thank you for your input people.
Looks like everybody agrees I should go the upgrade route.
