1. If it's a gaming build, drop the 1366 MoBo / CPU / memory and get something for 1155.
2. I wouldn't include anything that says Rosewill or Kingwin on it.

This is $2,069 and it includes a great case and superb PSU (HAF-X / XFX Black 850 would be an alternate to consider at about $45 more). MoBo is a great overclocker and has full 3 year warranty. 2500k is best bang for the buck, CPU cooler is way more than ya need for Sandy Bridge, SLI graphics (two cards) for $440, Vertex 3 is 50% faster than C300, monitor is 120 Hz

Two 560 GTX 900 Mhz will get you 862 fps in Guru3D's gaming test suite .... a single 580 gets 616, two 580's get's you
953..... you can get 10% more fps buying two 580's but it will cost you 227 % as much money.
