I have asked this question before but im going to make a vote too see what other people think. Should I keep my 670 FTW, buy another one and SLI them, or should i sell my 670 FTW and SLI the 770. Budget wise buying 2 new 770 is literally my borderline budget (a few dollars less then my budget). Please don't suggest me to get the 780 cause that is not going to happen. SO should i loose about 100 to 150 dollars and get two gtx 770 or should I just keep my existing 670 FTW and get another one?
