Hey so im getting my friend's GTX 780 6 gb and I would be perfectly fine with it as I currently have a 560ti 1 gb. But i'm looking into running the 780 in sli with another 780 is it worth buying another card or should I just buy a powerful single GPU and throw the GTX 780 in a LAN build? (This 780 in preticular is very good, getting +130 fps in BF1 medium.)
