so, two days ago i decided to go for gtx 780. but after reading forums and reviews from different sites, now im confused on what gpu upgrade would suite me. some say cfx 7970 will cost about the same price for gtx 780 and the preformance would likely be the same. some people say that gtx 770 is more than enough for the upcoming games.

btw i use my pc with two monitors, one for watching films on 1080p and the other on gaming on 1080p.

should i go for gtx 780? or cfx 79070 ghz edition? or just gtx 770? if u have some other ideas, im open for you suggestions :) even other cards
