I agree with what PiZZ4 said.
Also, I'd go with a better graphics card. I'd suggest the NVidia 560 Ti or the AMD 6950 (the 6970 is too expensive, not really worth the increase in power). The 560 and the 6950 are about the same speed and price but the 6950 has some room for overclocking if you like tweaking stuff.
Check out this from iBuyPower, it's pretty close to the one you're checking out but can be configured with a much better graphics card
http://www.ibuypower.com/Store/Intel_P67_Core_i5_i7_Configurator-set the processor to the i7-2600 (or 2600K if you want to overclock)
-they're doing free double RAM, so 8GB turns into 16GB
-set the graphics card to AMD 6950 (2GB) or NVidia 560 Ti (2GB)
-set the power supply to 700W Standard or 800W standard
-keep the 1TB hard drive they have set
-skip data drive, it's not needed with 1TB of primary space
-set the optical drive to whatever you want
Check the software page if you need a copy of Windows with it. Maybe you pirate or have an extra key or something
Support page gives you a free 3 year warranty
So I configured it to: i7-2600K, AMD 6950, 16GB RAM, 1TB hard drive, Blu-Ray drive, Windows 7, 3-year warranty, shipping = $1,345
slightly less than that one but with a much better GPU + warranty
