So i am trying to decide in getting 1 5870 or 2 5850s, i am running 3 monitors a 24,22,22. The 24 is 1920x1200 and the 22s are 1650x1080, i want to run them in eye infinidy and was wondering if i could even do that with the monitors being different resolutions and also if the best thing to do is go for the crossfire set up or just one 5870
