There isn't even that much of a performance difference to be fair. If a 970 can run AC:U with DSR at UHD resolutions with Ultra settings then I would go as far as saying it's almost a complete non issue.
Doesn't help people are looking at 980 performance, seeing the 970 is performing below ground there and putting 2+2 together and getting 6. Why they've neglected to divulge this information and choose this config is another matter though. Cost primarily I would think on available chips.
Pretty much this

Has any 970 owner on this forum had this issue?
This thread is giving me a headache
.obviously frame times would be nice to see on the 1 to 3% results to see if stutter is present.im sure the tech sites are on it now
