That actually is a nice computer. It could be built for a little cheaper if you did it yourself but if your not into doing that than that really isn't all that bad of a deal. It does have an I7 920, x58 chipset, 12GB's DDR3 ram, 1TB of storage, and dual 9800Gt's.
Im sure it will be up to anything you throw at it and later down the road it is very upgradable. Seems to be a pretty solid deal if you don't want to build it yourself.
