I just read through the first 50 pages and have a question ...
I am running a surround 3d setup and am choosing some video cards for 4 way sli

I am trying to determine if 2gb will be enough or 4gb be necessary

I was thinking to get 4 680 lightnings and overclock them with the voltage control and another option for a similar price would be the 4gb FTW or maybe the classifieds ...
Any thoughts , seems this is the right thread to ask

!!!
and to be clear as a 3d vision surround we are talking 3 1080p monitors ... my mb is the rampage extreme 4 (I will enable pcie 3) and my 3920 is clocked at 5ghz daily ...
I am considering things like fun of overclocking, importance of memory overclocking and how 2gb video memory will likely clock better than 4gb and total amount of video memory might or might not be necessary in top teir games like crysis 2 and BF3 and skyrim
