Building Computer, Need Help!

Anyways I am building a new computer - and I haven't really ever done this before so what I need help is with the parts in it, would all of these "work" together?

(All canadian prices)

Case: Antec Nine Hundred Ultimate Gamer Case

Motherboard: Asus P5B w/ DualDDR2 800, 7.1 Audio, Gigabit Lan, SATA II, PCI-E x16

Power Suppy: BFG PC System 650 Watt Power Supply w/ Dual +12V

Cpu: Intel Core™2 Duo Processor E6600 2.4GHz w/ 4MB Cache

Hard Drive: Seagate 320GB Barracuda 7200.10 SATA II w/ NCQ, 16MB Cache

Ram: OCZ 2GB PC2-6400 Gold Dual Channel DDR2 Kit (2 x 1GB)

With Vista, And for my Video Card I was thinking a G80 preferably a NVIDIA 8800 GTX. So that’s it - would all this work? I am open to suggestions / recommendations on things that I should change or need to add.

Thank you to anyone that helps!

change the RAM to 667 MHZ instead of 800
