I can't really understand how people recommend intel for purely gaming if its to be built on a budget. Sure if your dropping $3000 then its not unreasonable to drop 25-30% of your budget into the CPU+Chipset. But for cheaper rigs, not only will you save $20-40 on an AMD cpu, but you also save anywhere from $50-150 on a comparable motherboard, and another $30-50 for dual instead of triple channel ram (Assuming high end rig is i7)
Depends on how "budget" the budget is. My i5-750 and Biostar motherboard that is 8x/8x CFX and SLI capable together cost $240 brand new as a combo. To me, that was a bargain and priced equally to a Phenom II X4 BE and equivalent motherboard and the i5-750 is a better CPU for pretty much everything and used dual channel ram so no additional costs there. But honestly anything below the i5-750 (760 now) costs, I will go AMD every time.
Now also being said, my Phenom II X2 555 unlocked to essentially a X4 955 is a very solid CPU and is great for gaming. It overclocks pretty easily and is plenty fast for single card gaming with no real noticeable different between it and my i5 at 1920x1200 with eye candy turned up on a 5850. At $85 it has been one of my favorite purchases in a long time.
