CPU effect On Gaming...

post #1 of 5
Thread Starter 
I was wondering how big of an effect a CPU has on gaming if you have a good video card. I have a GTX 460 768Mb ram Superclocked edition along with 4GB of ram and an intel E7500 Core 2 Duo 2.93Ghz OC to 3.67Ghz. Now i was wondering if i were to upgrade the CPU(From socket 775 to a sandy bridge or I series) how large of an increase in performance would i see?

A CPU matters only if it is not fast enough to:
*send data to the GPU in a timely manner and the GPU must wait for textures and geometry
*compute the A.I. (only visible in strategy games on large maps w/ many players)

...so my take is that you could seen no gains or at best small gains. Your CPU is pretty fast, although it's a bit low on cache. It is very likely more than enough for the first task (feeding the GPU with data) while it may hold back in a 8-way skirmish in SC II. Benchmarks always see benefits in changing processors, however small, but these changes rarely reflect in real games.

yeah, not noticeable in gaming, but if you are doing emulation, virtual os, 3ds max, unreal dev kit, etc... then you will see a difference in cpu, and ram, but those are the only times you will notice that much difference from an increase in ram or processor speed

Okay so if i want to see more performance just upgrade to GTX 460 SLI x2 and keep my existing CPU?

that would be a viable option, but i do not see the point in going sli, i may be wrong but i don't think that most games use sli, and the ones that do, do not use it effectively
