Ivy Bridge upgradibility with that MoBo. PCIe 3.0 slots. i5 2400 since you wont be overclocking. HD 6970, can handle any game out there at max settings at 1080p. TX 750, can even handle HD 6970 Crossfire. Powerful PSU. HAF 912 is a great case for its price. Spinpoint F3 is a great, fast and quite drive.
You can cut the costs by getting a HD 6950 instead. ($130 lesser than the 6970)
I was wondering if I need that powerful of a power supply to support the system if I only use the 1 6970. I heard from other websites that you will be fine with a 600-650W. Is that true or is it better to just get the 750W just in case ?
