I'm building a gaming pc and was looking to get either a 780 or 780ti. However I've read that the 20nm maxwell 900 series gpus will be a huge jump in performance, noise, and thermals compared to the 700 series. And the 900 series is set to be released sometime next year. So my question is should I just go with a gtx 770 for right now and save my money for the 900 series? Will a gtx 770 be good enough for 1080p and at least 60 frames per second on most games coming out until then? I just don't want to buy a 780 so late with the next gen gpus coming out within a year. Any advice is appreciated. Thank you.
