So after a bunch of research, I'm pretty set on getting these parts. I just want to double check and make sure that all these parts are compatible with each other, and I have a case that is big enough to fit everything.
CPU/Processor: AMD Athlon II X4 640 Propus
Case: NZXT M59 Combo Link
Motherboard: GIGABYTE GA-870A-UD3
RAM:G.SKILL 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 Combo Link
Video Card: GIGABYTE GV-R577SO-1GD Radeon HD 5770 1GB
Power Supply: OCZ ModXStream Pro OCZ500MXSP 500W Combo Link
Thanks for the reply batuchka. That looks like a great setup, but I was really set on having a quad core processor. I'm pretty much a n00b at building PCs though so sometimes I don't trust what I am saying.
