Some components are a bit mismatched .....
Superb MoBo choice ..... might consider the Sabertooth for the 5 year warranty for $20 more. If it's just "gaming", the i5-3570 should suffice; if ya adding CAD, video editing and other apps that require HT, grab the i7-3770. In either case, you'll want the k version.
These combos will make up for the price difference between the Sabertooth and the Pro version
w/ 3570k save $20

w/ 3770k save $15
http://www.newegg.com/Product/ComboDealDetails.aspx?ItemList=Combo.975515
I'd grab the 3570k and put the $140 ya save into a better GFX card. However, if ya looking for big OC's , say above 4.6 Ghz, get a i5-2500k SB CPU
Forget CM for the PSU, thay have yet to make one worth buying, I'd look for a 9.5 to 10.0 performance rated PSU of 750 watts if not overclocking GPU's / CPU ..... 850 watts if ya OC'ing CPU / GPUs.

For a hard drive, the Barracuda XT series offers the best performance available from a 7200 RPM mechanical storage device.
Sound Card - Redundant, already on MoBo
GFX - Here's the numbers:
Guru3D uses the following games in their test suite: Hard Reset, COD-MW2, Far Cry 2, ANNO 1404, Metro 2033, ANNO 2070, BFBC2, BF3, Crysis 2, AvP, Lost Planet 2. Total fps (summing fps in each game @ 1920 x 1200) for the various options in parenthesis (single card / SL or CF) are tabulated below along with their cost in dollars per frame single card - CF or SLI:
Card - Cost ( Single / 2-way SLI /CF ) $ / Frame - $ / Frame SLI/CF
GTX 680 - $ 500 ( 989 / 1578 ) $ 0.51 - $ 0.63
680 DCII Cu TOP - $ 520 ( 1077 / NA ) $ 0.48 - ERR
GTX 670 - $ 400 ( 917 / 1539 ) $ 0.44 - $ 0.52
670 DCII Cu TOP - $ 430 ( 999 / 1679 ) $ 0.43 - $ 0.51
7970 - $ 480 ( 872 / NA ) $ 0.55 - ERR
7970 DCII Cu - $ 580 ( 924 / NA ) $ 0.63 - ERR
7950 - $ 400 ( 746 / NA ) $ 0.54 - ERR
7870 - $ 360 ( 701 / NA ) $ 0.51 - ERR
7850 - $ 260 ( 596 / NA ) $ 0.44 - ERR
7770 - $ 150 ( 375 / NA ) $ 0.40 - ERR
7750 - $ 110 ( 291 / NA ) $ 0.38 - ERR
In the table above for example, the Asus 670 Cu DCII TOP costs $430 each and gets 999 fps in single card configuration at a cost of $0.43 per frame and 1679 in SLI at a cost of $0.51 per frame. The AMD cards w/ NA did not complete all games in the test suite. This should be resolved in an upcoming driver fix. The nVidia card w/ NA was not tested in SLI.
Looking at the above, ya have to like the 670 ..... looking at the various offerings, ya have to love the Asus 670 DCII TOP
http://www.guru3d.com/article/evga-geforce-gtx-670-sc-review/23
EVGA gets 3DMark Score of 8691 outta the box and 9443 OC'd
Idle temp is 29C / load temp is 78C
Noise is 37 dBA Idle / 43 dBA under load
Asus gets 3DMark Score of 9340 outta the box and 9839 OC'd
Idle temp is 30C / load temp is 72C
Noise is 37 dBA Idle / 38 dBA under load
That makes the Asus OC'd card 7% faster outta the box than the other guy's OC, 6C cooler and almost 1/4 as loud under load (every 3 dBA is a doubling of sound level).
Those twin Asus 670's will give 2.4 times the performance ..... 1679 fps compared to the 701 for the 7870d.
Cooler - This depends on how high ya wanna go and what ya wanna spend.
$30 - Hyper 212 .....I wouldn't use on an overclocked IB CPU tho
