Take this as a personal preference but to my mind the following combos are the way to go:
If you may add a 2nd GFX card
Antec 1200 w/ SG-850 or CP-850, the latter being an extreme bargain.
CM HAF 952 w/ Corsair HX-750/850
Single card systems
Antec 900/902 w/ SG-650 / TP-650
CM HAF 922 w/ HX-620 or TX
Green drives save power but when speed matters, I'd go for the WD Black (2 TB Modle only) or any of the Seagate / Samsung drives w/ 500 GB (1 x 500, 2 x 500 or 3 x 500) platters depending on the size you want
Intel will be coming out with i9 processors using the 1366 socket in 2010. However, that does not mean that the i9 processors will work in the old X58 motherboards. The northbridge chipset on the X58 motherboards is an old design. I suspect Intel will be releasing new motherboard chipsets with the new i9 processors, but we will have to wait and see.
Very, very few people actually upgrade their Intel processors once they have built their system because Intel releases a new platform about every 18 months. The X58 platform is currently over one year old.
I just order my parts tonight for my it 920 build, so I've shopped for a lot of the stuff you are. My budget was a little lower than yours though. I went with the Antec 900 Tower that was $59.99 after rebate, as well as the Antec 750 PSU at $79.99 after rebate.
Oh, and if you're anywhere near a Microcenter, you can get the i7 920 for $199.99
