Ok since I recently fried my motherboard I am needing to rebuild. I use my computer for gaming. I have an Antec 900 case, Rosewill 750W, Seagate 1T HDD, WD 150G Raptor, Sceptre X24 monitor . I am running Windows 7 64bit Ultimate. I would like to stay around $500 for MB, CPU, GPU, and RAM. Is this posible? I have 2 9600GT cards that I can run SLI and upgrade later. I was thinking i5 with OC, but don't know about MB and RAM. Any recommendations?
