Cpu Bottlenecking

[Jono8]

Ok im thinking of going for a BFG 8800gtx oc2 but i only have a loly old x2 4400(man it got outdated fast).

Im worried about all this talk of bottlenecking but from what ive seen you only really get noticeable extra frames with something like a core 2 duo e6600 when playing at 800x600 or 1024x768 or with no AA or AF. Once you ramp the the resolution and image quality settings it doesnt seem to matter.

So my question is, as long as i keep the rez and AA/Af up in games (which is the reason im buying a gtx anyway) will it really matter?

Maybe i'm reading it wrong but you seem to have it the wrong way around.
You get less frames as you increase the res /AA?AF

well i mean for example if playing something like oblivion at 800x600 the framerate differemce between a top core 2 duo and my x2 would be quiet significant. But as soon as you play it at 1280x1024 with 8xAA and 16xAf for example the frame rate difference between the two become negligible. So i'm basically wondering whether my x2 would bottleneck the gtx that much considering i'll be playing at very high graphical settings.
