on that note aswel, 780i is ddr3 ram. so thats gonna cost a bundle.
unless you really have money to throw into the computer, get a decent motherboard with ddr2 support. the ddr2 ram prices are so cheap right now. it would also give you more money to spent on a better cpu say an e8500 and a better graphics card. say an 8800gt sli
its supposedly two 8800 gtx's linked together (sorry if im sounding pretty anal right now)i think the 9800GX2 is two 8800GT
