I recently bought a MSI Twin Frozr II 6870 as my budget is not as big as yours. Got Shogun 2 free with my newegg combo purchase and the 6870 can run it at max, as well as rift. So if you are worried about games not being able to handle it, well I would say have no fear. Getting a 6970 should hold you over for the next year or 2. And as far as the Twin Froze II goes, I have yet to hear any noise from it other then when I was installing windows.
