Ive been curious how many of you did this. I was going to, but I just don't have the heart to sell the 320m i got like 2 months ago at most for a loss of cash, just to get a card that prob wont be that much better for my needs. I play hl2 series, tf2, portal, bf, etc. rig in sig, i dont oc the card because its a htpc and dont need a lot of heat. but i have no issues, i run hl2 maxed 1440/900 16/16. why did you upgrade?
