I'm going to get a new computer, I am going to use the AMD FX8350 CPU, I want eyefinity on 3 monitors that are 1920x1080, so it should be a ATI/AMD card, which card should I choose? (It should have at least 3GB of memory and if a single card, about $680/£430/€510 and if 2 cards in crossfire about $340/£215/€255 each)
