I heard a major part of buying a gpu is asking yourself wether or not to buy now or wait for anything better to come out as there are so many new gpu's coming out lately. As a total noob, i've got no idea if there's anything better about to come out. Obviously you have the titan but that costs too much for me. So is there anything like the 780 Ti that's coming out soon or another version of the 780 Ti that's coming out soon? Or should I just buy one right now?
