Bottleneck, where's the limit?

post #1 of 2
Thread Starter 
So I've got a AMD Phenom II X4 965 overclocked to 3.8Ghz, northbridge at 2.6ghz.

I've been hearing lots of comment on other forums that this processor will be a bottleneck with my ATI Radeon HD 5870, but I've just ignored them knowing it won't be a bottleneck.

Recently I've been wondering about how and where to upgrade my computer.
Been looking at some Intel CPU's knowing they outperform my AMD, and Ive also been looking at some AMD 6970's.

Will my processor bottleneck AMD 6970 in crossfire? quadfire?
Where's the limit?

I had a 1055T in crossfire 6950s unlocked and didn't have a bottleneck so I doubt you will if just gaming. In benches my GPU score remained constant while switching to an i7 only affected my CPU scores. Heaven has remained the same as well since it's GPU based. Depending on what you play, I'd add an SSD to reduce load times or make things smoother if you play any MMOs. From what I have seen though, the only difference I came to was on the cpu portions of the benchmarks or in games that are CPU reliant. In these I saw the FPS difference but it's not visible to the eye because the difference is like 150 fps vs 160 fps. At that high framerate, you couldn't tell the difference.
