Hi, I need your help. I bought a asus rog matrix Platinum gtx 780 ti 2 weeks ago. Now i saw the good Performance of the gtx 980. So my question : is it worth it to upgrade from the 780 ti too gtx 980? I bought the asus 780 ti for only 400 Euro. Its a new card. So what would you say, send the asus back and buy a gtx 980? My System : Intel 4790k @4,8 GHz Asus rog matrix Platinum gtx 780 ti 8 GB DDR 3 RAM Win 8.1 Thank you in advance. And sorry my bad english.
