You do realise that damn powerful is about 2-3months away? The new AMD cards will launch around Windows 7.
Also the PSU you chose can't run Tri SLI because it only has 4 PCI-E power adapters. Sorry! 
Oh yeah and the cheaper Corei5 mainstream motherboard/CPUs are coming out, if you aren't looking to overclock...
Oh and the HDD you chose is a little small, you should get 1000GB because games are starting to chew through 20+GB of space.
Tease.
