I want to buy and build a new computer but have never done it on my own before. Before I buy all the Hardware from Newegg, I thought I would list them on here so anyone can warn me if I am making a mistake. Any advice is appreciated.
Case: Antec Nine Hundred Black Steel ATX Mid Tower
Power: Antec EA650 650W ATX12V Ver.2.2 / EPS12V version 2.91
MotherBoard: ASUS M4A79 Deluxe AM2+/AM2 AMD 790FX ATX AMD
CPU: AMD Phenom II X4 940 Deneb 3.0GHz 4 x 512KB L2 Cache 6MB L3 Cache Socket AM2+ 125W Quad-Core Black Edition Processor
Memory: 4 x G.SKILL 2GB 240-Pin DDR2 SDRAM DDR2 800

Also, since 32bit windows only recognizes up to 3gig ram I need to upgrade. I have XP home right now. Should I upgrade to 64bit XP or go to 64bit Vista? Thanks for any help.
