I would suggest:

i7 920 D0
EVGA x58 Classified
Corsair DOminator GT 6gb
Samsung F3 Spinpoint 1tb - the fastest hard drive that is non solid state, even proven to beat the velociraptor in everything but random access.
HAF932
Prolimatech Megahalems cooler
2x 5870 1gb (don't get the 2gb)
Corsair 850HX PSU
2x Scythe Ultra Kaze Fans for the megahalems. Probs 2k rpm will be the best.

If you can afford it:
Another F3 spinpoint and RAID0 them
Intel x25M G2 80gb SSD OR OCZ Vertex 120gb SSD


Then get a nice screen, Dell 24" monitors are very nice, although a little pricey. GEt a rokkat kova for your mouse, and an Enermax Aurora for your keyboard.
