I am looking to replace my GPU as cost effectively as possible and found a couple 7970's on CL for between $140-$160. My main concern is that I want to know if the 7970 is still a capable 1080P card as it is quite dated now. Should It remain viable for the forseable future or should I save more money and get a 290 or something from the 3XX line ? I was going to go nvidia but the 960 was a flop and the 970 is overkill plus they lied about it which kind of puts me off. There are 770's on CL for around $200, are these a good deal ?
