I was wondering if I could possibly upgrade my 4gb DDR2 to 8gb DDR2, and my CPU to a C2Q Q6600 to make a neato semi $100 gaming rig (for lower end games anyways). And would the motherboard support a GTX 650. I'm upgrading the Dell Optiplex 780 in case you want to know. The motherboard is a Dell 0200DY. If the motherboard can't support all 3 parts, I'll just get a new one.
