What is that motherboard? You need at least a half decent mobo...maybe this if you really need a cheap one:
This processor is great for the price if you don't get the quad:
OCZ PSUs...eh. Unless you really want the silent PSU, I'd get this instead:
OCZ RAM is pretty good, and that's the cheapest...so I'd go with that. I've had nothing but a good experience with OCZ RAM.
You basically just have to balance your build out more. I mean a quad core with some crappy mATX motherboard?
