I have a gtx 970, I want to know if I should buy another 970 or go with a 980 ti and give this card to my friend instead of him getting a 960. He plans on playing fallout 4 at 1080p with high settings. I plan on going to 1440p with 144hz, bearing in mind that I can only get one ti, is it better to just save up for the ti? Or just get another gtx 970?
