Why don't you go with 2 way SLI of GTX580 instead of Radeon HD 6970? The GTX580 is the best card out there right, i would even buy a GTX570 instead of the 6970. Also, stick to a I7-950 or if you are hardcore, choose a I7-965 Extreme Edition. About the RAM, go with Corsair Dominator 2000MHz if you want that much or just stick to the 1600MHz version of them. Why do you need to overkill your PC so much? I don't really see which games need all that power? If i were you i would just choose a simple, but cheap(er) system. Here is my list: GTX 580 (2x of this, if you want to go SLI, i recommend EVGA or MSI) 6GB DDR3 1600MHz (I recommend Corsair) I7-950 PSU: 1000 Watt (Corsair, Antec) Motherboard: EVGA X58 FTW3 Windows 7 (Explain why you need Ultimate?) Case: Antec 1200 or Coolermaster HAF 932 Buy a SSD (Intel X25-V is fine) to have your OS on and then a 1TB HDD storage drive. That's my list of a reasonable computer.
