I have a 775 pin 6850 core2 duo 3 gig processor and I believe a Nvidia geforce 8800 gts with 512mb and I was considering either upgrading to a nvidia 285 card or getting new motherboard and intel 920 and DDR 3 memory? Which do you think would be better I don't have a whole lot of money right now! Card is around 300 or 350 if I go the other option it's going to be around 700.
