I have been saving money for two GTX 680s on SLI, but recently there have been many rumors on the release of the 700 series. Should I save my money and wait for it considering the fact that I have to wait till more models of it come out. If so I am interested in a dual 780 or 770 on SLI. So do you think I should wait cause I dont want to waste my money? What are your thoughts?
