I currently have a gtx 780 s.jetsream, planning to swap it for an r9 290 and i plan to go for a 2 or 3 monitor set up 1920x1080. I know for sure that an r9 290 with good cooling can kill a 780 but at the cost of a bit more voltage. And i also know that a 780 with high clocks can match an r9 290 with less voltage. Which is better for my setup? Please enlighten me my brothers
