Well, up to the 955BE. They pretty much own the $50-$100 segment and make sense up to the 955 which is around $160 I believe. Intel's i3, for $130, competes alot better than I thought it would, especially if you overclock it. The X3 and X4's around that price are still good though. For a little more you start looking at an i5 750 (which is an excellent overclocker). If your total budget is $1000 or less, then AMD is a good choice depending on what you want to do. For $1000-1300 it just kind of depends, and above $1300 I pretty much say an i7 920/930 build all the way
