I have 600 bucks
I have 400 dollars right now. Tomorrow, I'm going to buy the BFG 7800 GT for 350$. I have a 15% of my purchase gets turned into a gift card thingy, so I'll get around 50 bucks in a circuit city gift card. I am selling my old graphics card, a Radeon 9800 Pro, for 100 bucks, to a freind. I also have a processor that I bought a month or so ago that I cant use for around 150 bucks. So I have 300 dollars, 50 of which I can only use at circuit city, to spend on a motherboard, processor, and RAM. What should I do?
EDIT: I'm building a gaming computer just in case you needed that too.
