Well no..
That usually applies with cores, games right now can't handle Quads yet, but games are becoming Quad Intensive, so heres a good build for $1,200
Q6600
Asus P5Q Pro
HD 4870 Crossfire (or HD 4870 with HD 4870X2)
4gb DDR2 Kit
Case, HD, Optical Drives of your choice
But depending on which games you play this is highly overboard
EDIT: please don't Quadruple post, use the Edit Feature in the future, consecutive posts within the 24 hour period is considered Spam
EDIT2: AMD is currently slower than Intel in the CPU market (they overclock better too), so stick with Intel
