Thanks for the responses so far, this has helped a lot. I went out today to Fry's Electronics who are having a sale on the 920 for $220, $250 with tax. I also went ahead and bought the Corsair 750 PSU for $90. Right now things look good:
Intel i7 920 - $220
EVGA X58 Mobo - $300
EVGA GTX260 Core 216 - $250
G.Skill 4GB(2x2GB) DDR3 1333 - $87 (this seems TOO cheap for memory, is there something I'm missing here? link
CORSAIR CMPSU-750TX 750W - $90
2x WD Caviar SE16 500GB in Raid1 - $130
Antec 900 Black Case - $110
V8 CPU Cooler - $70 (any alternatives, this is sold out?)
Arctic Silver 5 Thermal Compound - $6
All together, with tax and shipping I'm around $1,350. If there is anything else I've forgotten, let me know. I want this rig up and running a couple of hours tops after I get my package from newegg. Although newegg is being glitchy right now, showing nearly everything as out of stock.
Edit: They fixed the stock issue, but the V8 seems to be out of stock.
