Should I SLI my 2GB 770 or upgrade?

[OGBobbyJohnson]

So I've got a EVGA Superclocked 770 and was wondering wether I should drop some cash on upgrading or just getting another 2GB 770 and putting it into SLI? I'm going to be playing Arma 3, and BF1 and probably other good titles coming up.

It would be best to upgrade to a single better performing card , the 1060 is just around the corner and looks to be a great performer yet being more affordable than a 1070/1080. The 2GB vram will limit you if you went 770 SLI.
Depends what res you are playing at, if you are at 1080p look at a 1060 or if you play at a higher res go for the 1070

Or a 980ti if you can get it new for cheaper than an 1070.
