I am looking to to upgrade my GPU and was wondering what GPU would be the best for the price. I am willing to spend between $300 to around $600. I play games like DayZ, Bioshock infinite, GTA v, metro last light redux, and looking to get assassins creed unity, dead island 2 and possibly splinter cell blacklist, and GTA iv with a lot of mods. I was looking at the gtx 970 and 980 but I'm not sure that I need to spend the money to play the games I do, do the added features like downsampling and other stuff add to the value of the card, or would I be able to get a gtx 780ti for a better price to performance ration. Or should I look at amd? Any help will be great!
