I have a r9 280 one fan is starting to fail/make a lot of noise and racket when I watch twitch or play a game or both at the same time. I have made up my mind to replace it though I only have a budget for a 950 GTX will this card do for gaming at 2560x1080? I Play games like DAI witcher 3 mordor borderlands etc also alot of lower end games. I also only have a 520 seasonic psu and yea I won't be able to replace the psu.
