Upgrade Comp.

I'm gonna upgrade my comp in a few weeks, and I was wondering if I would encounter any problems with my upgrades.

MSI P35 Neo2-FR Motherboard,

Intel Core 2 Quad Q6600,

Palit Sonic HD4870 1GB Dual Edition,

Asustek TA-M1 (or M11) casing,

Cooler Master RS-550M 550W Real Power PSU.

2GB Ram + DVD-Drive + Hard Disk , will be salvaged from my old CPU.
