Case / PSU
$230 Antec 1200 w/ CP-850
http://www.newegg.com/Product/ComboDealDetails.aspx?Ite...
Why - The Antec 1200 and HAF 932 are the de facto THG favorites. Both trade pluses and minuses and it usually comes down to a styling choice. If going w/ twin GFX cards, grab the two optional case fans. The CP-850 simply has no competition in it's price range. Of the four 850 watters that get a 10.0 performance rating on jonnyguru.com, the Antec SG-850 and the CP-850 also get Editors Choice selections on jonnyguru.com
MoBo / CPU
$520 ASUS P6X58D-E w/ Intel i7-930
http://www.newegg.com/Product/ComboDealDetails.aspx?Ite...
Why - Great board, $90 cheaper than it's dual LAN big brother. See alternate OC monster below.
RAM
$200 3 x 2GB Corsair DDR3-1600 CAS 7
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Why - it's low profile so wo't interfere w/ heat sinks and has slightly faster timings the the $190 GSkill.
Hard Drive
$85 Seagate Barracuda 7200.12 1TB
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Why - given your usage the 7200 is the pick of choice oiver the F3 ... the 72000 excels in gaming, pictures and multimedia whereas the F3 is the better choice for movies and music. The 7200 is also much quieter (1/4th as load as the F3) and runs a lot cooler.
Heat Sink
$65 Megahalmes Rev B

$7 IC Diamond 7 Karat

Scyth PWM Fans $11 x 2

$7 PWM Y Cable Splitter
http://www.frozencpu.com/products/8418/cab-150/FrozenCP...
Why - I used to post a series of test sites saying to pick from the top 5.....now it's just do you spend $50 for a very good cooler or spend $100 for the best. For performance and ease of installation, the Prolimatech Megahalems IS tops both criteria.
If ya find $100 too much, the Scyth Mugen 2 SCMG-2000 is the way to go.

Optical Drive
If that's not in your future, $25 Any DVD writer will do
GFX Cards
$350 Asus ENGTX470/2DI/1280MD5 GTX 470 (Fermi)
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
.....or
$320 ASUS EAH5850 DIRECTCU/2DIS/1GD5 HD 5850
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Why - If ya have the case for adequate cooling and the PSU to push it, the 470 offers a very attractive "dollars per frame" . Here's a tabulation of cards to consider based upon 9 DX11 benchmark by THG and HardwareCanucks at 1920 x 1200 and high settings:
ATI 5970 11.93
nVidi 480 10.01
nVidia 470 9.08
ATI 5870 10.59
ATI 5850 9.04
The dollars per frame is expected to increase with performance due to the law of diminishing returns....but the 470 is so close to the 5850 in price / performance ratio, the extra $30-50 make sense. It also finished on top in 8 outta 9 of those benchmarks. However if your primary usage is older DX9/10 games, then the 5850has a much stronger showing. To my mind, it's hard to find fault w/ either choice.
PSU can handle twin cards if ya want SLI / XFire
$1481-1511 w/ single GFX card
If you want a board with every possible overclocking feature, the new Rampage III Extreme is amazing. Then again, at $380 it should be expected to be. I'd drop the extra money ($170) in a heartbeat.

Personally, I'd go with the R3E and one 470 and add another 470 for XMas.
