Sadly AMD had to be chumps and aren't planning on releasing high performance cards to rival Nvidia Pascal, so I'm going team green again. I already have a 970, I know the Pascal cards will be down on a smaller node, so that would probably bring huge improvements and all, but think SLI'd 970's would be better performance wise than a 1080? I don't think it would be worthwhile to upgrade to only a 1070, might as well get 60% more performance if I'm spending $5-600.
