id go for the 2gb for sure. you will almost never run into vram problems with 2gb at 1920x1080.
please stop giving people shit advice and making people waste fucking money!! did you never take future games into consideration! I hope you's guy's didn't listen to him because next gen is here!. cod ghosts using more than 3gb vram, bf4 is also using more than 2gb vram and this is just the start of next gen! do not listen to these 2gb morons because it isn't going to be enough think ahead.http://www.youtube.com/watch?v=0HDaz2gsTwg
