I can't see investing in a hi end MoBo and more expensive RAM of you are not going to OC...really no need for anything more than DDR3-1033
CPU / Cooler - If you are going to OC, look at this combo.....
Here's the 950 w/ Prolimatech CPU cooler ($15 savings)

Why the Mega ? It's simply outperforms everything else including the Zalmann

Don't forget the TIM - $5

See the comparison of all fou boards here ..... between the Giga and the Asus Formula, I'd take the Formula ... it gets an extra egg over the Giga in the newegg ratings but see if ya need all the feautures of a $290 board and opt for something less expensive if ya don't need 'em

RAM - Corsair Memory has too long been riding on it's name and there are other choices. Some are just cheaper, some are cheaper with hi quality. Of late, Mushkin to my mind is offering the best price / performance option. I'd pick your overclock and then choose memory accordingly:
No overclock - DDR3-1066
Up to 25 % overclock - DDR3-1333
Up to 50% overclock - DDR-1600
The way this works is best explained here:
http://vip.asus.com/forum/view.aspx?id=20081220191040237&board_id=1&model=P6T+Deluxe&page=1&SLanguage=en-us
In short, your default BCLK is 133 (133.33)
133 x 24 CPU multiplier = 3.2 Ghz CPU speed
133 x 8 memory multiplier = 1066 Memory Speed
At 25% OC, BCLK gets increased to 167
167 x 24 CPU multiplier = 4.0 Ghz CPU speed
167 x 8 memory multiplier = 1333Memory Speed (requires DDR3-1333)
With the 950, a 25% CPU OC is pretty much readily obtained with any good air cooler. If you're new to overlcocking, ya might wanna stop there. Another option would be:
At 25% OC, BCLK gets increased to 167
160 x 24 CPU multiplier = 3.84 Ghz CPU speed
160 x 10 memory multiplier = 1600Memory Speed (requires DDR3-1600)
After the DDR speed, the next choice is CAS setting, lower is better / faster. This is pretty much a price / performance choice depending on pricing "at the time". If it were me, for the 950, I'd go with 160 BCLK and 10 memory multiplier. That would mean DDR3-1600.
CAS 6 - These two Mushkin choices are $2 apart ($180 and $178 shipped). There was a nice discount thru yesterday but gone now. The OCZ Reapers are a bit cheaper but look a bit tall and might interfere w/ your CPU cooler.

CAS 7 - These Mushkins ate $110 .... At $70 savings, I'd give up the CAS 6 and get these.
CAS 8 - These corsair's are $135 but at $25 more than the above, that seals the deal for the CAS 7's.

GFX Card - Thanks to the release of the 6xxx series by ATI, the 470 has again dropped in price where it remains the "no brainer" choice. The 6xxx is competitive but just doesn't quite get to the 470's performance level.

Here is the bottom line: the Radeon HD 6850 is almost as fast as the GeForce GTX 460 1 GB, and the Radeon HD 6870 is almost as fast as the GeForce GTX 470.
The size PSU you hve chosen (850 watts) is more than enough for twin 470's so that's not going t be an issue.
Case / PSU - I'm starting an Antec DF-85 build tomorrow and will let you know how it turns out, but you've taken a significant step down with the PSU choice. The Corsair HX-850 would be a comparable choice but that case is specifically built to house an Antec CP-850 which is both quieter and better performer than the Corsair TX series. The reviews are quite conclusive. Jonnyguru gives the CP-850- a 10.0 "Performance Rating" (Corsair TX gets a 9.5). Only three four 850 watts PSU's make silentpcreview.com's Editor's Choice List ... Corsair AX850 / Seasonic M12D 850W / Antec CP-850 / Antec Signature 850

This PSU uses the CPX form factor which is unique to Antec hi-end cases. It's a larger size which gives the engineers room for "bigger and better" stuff, better cooling and quieter operation. Since the DF-85 is one of the few cases which can accommodate the CPX form factor, it would be a shame to waste the opportunity to take advantage of what it offers.
SSD - Faster boot launch times but adds little to gaming, still I see it as a worthwhile addition .... at up to $200 or so for a $120 GB size. Also, unless you gonna utilize the hot swap thingie on the DF-85 for ya bot drive, I'd get a 3.5 model. Check out the Vertex 2 alternative at $205

Monitor - You listed either 1920 x 1200 or 1920 x 1080 as your choice....having both, I'd suggest the 1920 x 1200.....you'll get to love playing games or watching movies at 1920 x 1080 and still having your task bar and other doo dads visible at the bottom of the screen.
Hard Drive - 120 GB ain't goinna be enough. The Seagate 7200.12 and Spinpoint F3 are great choices but at $15 off for the 1 TB F3, ($54) it's another "no brainer".
