Hello i am building a pc and plan on buying 2 gtx 780s for sli.I will be playing on a single 1920x1200 monitor and will use another monitor for youtube and stuff while gaming.Question is some say 780 sli is over kill for single monitor but i look at the single 780 benchmarks and it cant run crysis 3 at 60 fps?And i want it to run the upcoming BF4 at atleast 60 fps with ultra settings and am not sure if a single 780 could do that.Can you guys help me chosse between sli and single card?
