The mobo will do but the only thing is that you should not count the video card and buy the 6800 GS. How much is Alienware asking for the 6200 TC ( Turbo Cache, is just a way the video card relays information from the video card memory to system memory when it needs to, which means that the video card doesn't actually perform quicker, it has larger areas to swap information easier no real gain in performance though!
