Around $800 PC

I'm looking to build a PC around $800, and I pretty much followed the guidelines from one of the videos. I chose the following: AMD Phenom II x4 BE, 8GB Corsair Vengence RAM, Gigabyte GA-990FX-UD3 Motherboard, HIS 7870 IceQ video card, NZXT Source 210 case, Cooler Master eXtreme Power 500W Power Supply, WD Blue 1TB Hard Drive, and Windows 7 Home Premium. What do we think? I don't have much more cash to do any improvements price wise, however, any pointers are cheaper/better components would be appreciated. Thanks!

830 USD still OK, if so then I would get this: http://pcpartpicker.com/p/SVM2

A lot of fps for the price I'd say, and a step up from the Phenom II X4 and the 7870, plus a high airflow gaming case with classic looks and individual fan control and a good power supply that will suffice for that build, even overclocked, and a high performance cooler.

I've done a billion of these things today, I'll make one tomorrow, time for some sappy ass manga and anime

if you want to buy the 7870 XT from superbiz go ahead it is faster than the 7870Ghz that I linked for the same price, I just don't like buying from unfamilar places
