I'm looking to play Aion with very high framerate, in very crowded spaces with lots of stuff going on, on full graphics. Thats about it though, so I dont want to spend a whole bunch of money on something I don't need. I'm getting four gigs of ram (Corsair Dominator) and a AMD Phenom II X4 965 Black Edition, so that's figured out. Which one of these is best?
