New Intel System?

After much consideration, and a couple of post here, I've finally decided on new system components.
I'd like any input as to whether all this seems compatible (reasonable):

INTEL BX80569Q9550 Core 2 Quad Q9550 2.83 GHz 1333 MHz Socket 775 2 x 6MB Desktop Processor
2 X OCZ OCZ2RPR10664GK 4GB PC2-8500 (DDR2-1066) DDR2 Memory
ASUS Maximus II Formula Intel P45 MHz PC2-9600 (DDR2-1200) ATX Motherboard
LG GH22LS30 22X SATA DVD Burner Black Drive Bulk
BFG BFGEGTX2801024OC2E Geforce GTX 280 1GB GDDR3 PCI Express x16 (2.0v) Video Card

Existing parts:

Antec P180 case
Corsair HX620 power supply
2 X WD 74GB Raptors (RAID 0)
Seagate 320 GB SATA (Storage)
WD 36GB Raptor (Photoshop Scratch)

I realize I will not be able to SLI Nvidia video cards in the future with this chipset.

Ran a couple power supply calculators, the HX620 should be fine.

Memory not on ASUS QVL, but others have reported good results with it.

Motherboard may be a bit overkill, but I based my selected on Newegg user
reviews in comparison to other boards. Suggestions here definitely appreciated.

Replacing AMD 5200+ on ASUS M2N-E with 4GB PC800 memory and Geforce
8800 GTS (640MB version).

I decided against the NVidia 790i chipset because of the price of "performance" DDR3.
Didn't go with the X48 chipset because I won't need the 2 X 16 Crossfire link. I won't be
overclocking beyond 3 GHz, which the P45 seems capable of. Will be using the onboard
sound, at least to evaluate the Supreme X-Fi, add sound card later if needed.

Thanks for your time-
Fitz (hoping for some input before pressing the "Purchase" button)
