So I am selling my vapor x r9 290x's that I had in crossfire because of amd's driver issues and they never to seem to run a constant frame. I want to switch to nvidia and was looking at the 970's, was wondering if this is a good trade off, I'll probably get two of whatever card I get, I was comparing my old card to the 970 and the specs do seem to be lower, streaming processors 1664 compared to 2816 and core clock is lower. I have a 4k monitor so as long as I'm able to run max settings on 4k would the 970 be a good card or should I get something else?
