Ok I am going to get the nvidia 680i motherboard and was wondering if I had to get ddr2 1200 RAM. Cause I already have some RAM and would like to put it on the MOBO and 1200 RAM is very expensive. Can I use like ddr2 800 or something. Will I see a dramatic increase in power if I use DDR2 1200. Also I am going to pretty much only game and was wondering if 2gb or memory would be enough for running vista and games and some photoshop. Thank you for reading!!!
