At lower resolutions, you are shifting the burden more to the CPU.
When we get high end cards, we generally want the work load to be shifted to the GPU, that way the CPU isn't limiting performace. How do we do that? jack up the resolution...

Or/and jack up the eye-candy.... AA, AS, HDR, textures, etc.

So your C2D or overclocked X2 maybe bottleneck a 8800GTX at 1280x1024. However, you can really jack up the eye-candy settings the bottleneck will be reduced. The free power of the graphics card is now put to use.
Once again...

I found that overclocking AMDs don't do much in terms of performance gains, unless you can get to 3.0 Ghz stable. I'm just running everything stock, migt jump to C2D or better soon!

If you run games at a resolution greater then 1280x1024 then no.

However if you are running resolutions lower then that (and if you are with that card you deserve to be beaten) then yes.

I gained an extra 6FPS in Half-Life 2:Lost Coast with a 200MHz increase in clock speed...
