Solid build. Have the same board running 24/7 4.5GHz from day one with a cheap cooler and no hiccups (the mobo is a little thin), except that the Vcore Offset voltage setting requires higher volts than the Auto setting to get it stable, go figure.
You can also check out Gigabyte's UD3H
SSDs are fairly cheap right now so you can have one as a boot drive and a couple of your favorite games (it makes a nice difference).Sammy 840Pro
120GB for 139$ is a good choice.
660Ti is a great card at an ok price, but you can get the 7950 for 269$
with Crysis3 & Bioshock.
PSU wise, the Antec HCG is a decent unit but a bit old, you can get the Capstone 650M
for 74$ which is enough for 2 high-end GPUs oc'ed.
Last, if you're using the rig just for gaming, you might be better off with W7 instead of 8.....
