So I have 2x512@667 currently but managed to snag a 1gb stick @800. I believe running 2x512 in dual is better than 1gb in single but would sticking in the 1gb stick to jump to 2gb total (running in single channel?) be better than yet. I play Titan Quest right now but in the near future will be moving on to Oblivion. I all ready made the mistake of getting a 8800gts 320 and I game @1600x1200. Some games that I play/played lag slightly and I can't really run AA because of the low vram. So, back to the main question 1 + 2x512 better than 2x512 or not?
