I am always jealous of how much you American's have things cheap. In Australia, a rig like that would be 2 and a half grand...
Anyway, enough grumbling.
The rig looks perfect, only thing I can see is changing to Low Profile RAM in case you want to upgrade to 16GB. G.Skill Ares or Corsair Vengeance Low Profile are the kits to get.
You havent selected a mouse and you seem to indicate you need one. The Razer Deathadder is great mouse, I have one personally and its the best I'v had. You can even get left hand versions if your so inclined.
A good board and Power supply are must's looks like you did your research, If nothing else is brand new the PSU and motherboard should be when spending that much money. I would also recommend ASUS monitors as they are also popular.
Buying it all from newegg will increase the price a lot on Troll's build, but it will still be cheaper than bigcyco's. I'd say that since bigcyco's build is mostly MIRs, and since those rarely work out, Troll's build will be a better bet. Just my opinion though, so don't take it as hatred.
