You're correct - you need to move up to about the 2.8- 3.0GHZ level (or close) with AMD to get better FPS, otherwise you'll likely have about a 10-15-20 % ( game situational and res depending) performance level bottleneck comparatively.
Even at 1280x1024?
Generally the lower the res (I know it sounds wrong) the more that the better CPU will show it's speed in pure FPS terms. If you played @ 16*10 the more the burden would shift to the GPU (not totally but moreso). For example, the E6850 has an astounding FPS speed difference against the AMD 6000+ X2 @ the lower resolutions (1024x768-1152x864) but once the resolutions are increased to wide screen 16*10 the gap narrows dramatically to only about a 1-3% advantage with both running the same GPU, but the speed difference between your CPU @ 2.4 and an E6750-8400 at lower resolutions will be quite dramatic, and even against a 6000+ @ 3.0ghz. At 1280x1024 it's a bit better though, but you eventually need to get a faster CPU.
That is true and I understand that, but that's not Bottle Necking the Video Card. That's just plain Bottle Necking.
The bottle-necking has to have variable. The variable most affected would be the GPU
via the CPU - comparatively against the gain that a better CPU would get with the same card. That said, there's nothing wrong with slapping and 8800GT on that system regardless of the % of any bottleneck - the gains you get from overall performance benefit outway any miniscule misbalance on way or the other.
The variable is Performance. The GPU is not being held back by the CPU resulting in the end performance in this case. The end result is merely due to the CPU being unable to keep up with the demands of the Software, not the demands of the GPU.
The result of the variables I mentioned are cause / effect and the effect of the combined variable is the overall performance, the primarily variable/s is the hardware mentioned not the software. It takes hardware to run software, so your primary variable is the hardware. The GPU is held back "comparatively" - key word "comparatively". It isn't so much about the demands of the GPU, but rather the CPU bottle-necking the GPU to an "extent". Take the same GPU and sit it on an E6850 - test from 800x600 through 1280x1024. Massive FPS differences you
will see. Raise that res to 1680x1050 up through 19*12 and you will still see a fairly sizable difference though getting smaller from 16*10 then to 19*12. That gap would be further closed at higher resolutions if he had a better CPU.
That said - no reason he can't use even an HD4850 for a while with the 3800X2. The gains would still be worth it despite any bottle-necking.
