The mother only supports dd2, and it came with the ddr2 800 ram. So when I went to by some extra ram so that it would be 4gb the ddr2 1066 was actually cheaper so that's why there the two types of ram, and i know that the 1066 gets down clocked to 800 because of the other ram. Also, the phenom one is a mistake i know, I realized it after i sent in the order . The Sony CD/DVD is a DVD+/-RW, and i bought that gpu for the 256 bit interface, and to my surprise its actually a well rated card and gets good benchmarking scores. So overall even tho this build might seem a little bad it still gets really really good benchmarking scores. Thanks for your advice, ill remember it when i upgrade any of those parts.
Well, I don't need to 6 cores but it's just a little bit more expensive so I thought why not just buy it. Also, this computer is going to be mainly used for gaming (a lot of racing simulators) and everyday use. Thanks for mentioning the HD6xxx series because there not much more expensive so i think i'll go with a "XFX HD-685X-ZNFC Radeon HD 6850 1GB 256-bit DDR5 PCI Express 2.1 x16 HDCP Ready CrossFireX". I think the ram is compatible but ill have to do more research. Finaly, the hdd isn't a big deal for me so i took the cheapest one, because ill end up getting a 1tb drive afterward.
