So I'm buying a computer from Ibuypower and I'm trying to decide what video card set up I should get. I could 3 way sli some 760's, 2 way sli superclocked 760s, pay a little less and get 1 770, or pay a little more and get a 780. I feel like saving a hundred bucks and getting the sli seems like a good idea but I'm not sure. What do you think?
