I currently have an i5-2500k at 3.3GHz and a gtx 770 2gb. I am looking to pick up 3 BenQ 144hz monitors whenever they come out with the GSync integrated into them. I want to be able to pull atleast 60fps with triple monitors on games like Battlefield 4 or Crysis 3 and 120+ fps with games that take less GPU power like minecraft, CSGO, etc. I would prefer to buy a second 2gb 770 and SLI them, however I have read that for that resolution 2gb of VRAM won't be enough. I could sell my 2gb 770 and get two 4gb 770s, however for that price I could go get one 780ti 3gb. So my questions are...
1. Would a 770 2gb SLI not have enough VRAM for 5760x1080 with games like BF4? This is my preferred plan as I already have one of the 770s
2. If a 2gb SLI won't be enough, could I get two 770 4gb cards and SLI them and achieve those FPS or will the 256bit memory interface be a bottleneck?
3. Seeing as I would prefer a single card setup as opposed to a 2way SLI setup would a 780ti 3gb be a better option as I could always SLI another later? I know two 770s would have a bit more performance, but I would spend the same amount since I have to buy two 770s as I don't have a 4gb version.
4. Would 3gb in a 780ti be enough for the future or am I going to run into the same problem as I have now with a 2gb 770?
