hey guys, I am needing a new graphics card, I will be using three monitors for my driving games, but will also be playing bf4. I am planning on buying amd's 7950 card or maybe 2, my question is this, do I buy just 1 card with 3gig of memory or 2 with 6 gig, if I run 2 cards what are the issues with crossfire ? and do I really need 2 cards to run 3 monitors and run bf4 on high settings, I wont be running bf4 with 3 monitors. I have heard conflicting info so any help would be really appreciated
