how about getting the athlon phenom II x3 715 over the x3 445??
Can't beat that at $71.
Combo deals look pretty light today - Here is an Asus M4A785TD-V / W7-64 OS combo
for $180.GSkill 6GB (3 x 2GB) DDR3 1333
Around $450 with your cooler. I suspect it will run 14x250MHz without too much problem. Might unlock, too, but 3 fast cores at 3.5GHz/2500MHz IMC would cut like buddah
