Is there a big difference between HDMI and DVI? I am wondering this because I was going to get an Acer 23" Monitor that has HDMI and 1080p but I dont think my XFX Radeon HD 6870 and AMD Athlon II x3 will be able to run high settings on BF3 or will it? But other than that i found an Acer 20" monitor that is 1600 x 900 but it only has DVI and I think that BF3 will run better but what are your opinions? Do think BF3 will run on the 1080p one or should I should I get the other?
