In correspondence with my recent thread about upgrading my friends old computer, I think it's about time I get a little upgrade for mine. Mine's a lot newer and a lot less needing of an upgrade, but I got some spare cash, so might as well.
System Model: MS-7599
Processor: AMD Phenom(tm) II X4 955 Processor (4 CPUs), ~3.2GHz
Memory: 8GB DDR3 (4GB X2, two spare slots left)
GPU: AMD Radeon HD 6950 2GB
I'm only going to upgrade one part, so which one needs upgrading most do you think?
