Would a C2Q Q9550 overclocked at 3.2-3.8 GHz, 4 gigs of DDR2 1066, and a 4870 x2 be enough to balance each other out so neither bottleneck? I'll also be using the set up on a 30" monitor running at 2560 x 1600.
From what I understand, any quad over 3.0Ghz will not bottleneck your GPU. At such a high resolution, only your GPU can really be the bottleneck, even though it's super powerful.
