Also, if you're looking for place to compare performance against, I'd steer clear of techpowerup for one simple reason: they don't disclose what settings they used to test with. The only say if they disabled on particular feature (Hairworks, for example) and then they just spew a number for a resolution. No notes about what settings preset they used, just chart after chart of meaningless gibberish. They used to be pretty good about including details (old Tomb Raider tests would say "we used ultra preset, 4xMSAA, no TressFX"), but lately they border on worthless.
Guru3d and HardOCP both do well to explain settings and how to replicate tests. They also illustrate how taxing specific settings can be. Guru3d doesn't use ultra godrays and shadows in their Fallout 4 testing at 1440p, while H does. This shows that just that bump alone drops a 1070/980ti from 85 fps to 58.
Guru does well to display several cards at common settings, no looking to optimize speicifically. Lots of different cards at several resolutions, all using a common preset. Good to see approximately what you can expect.
HardOCP focuses on taking the best of what a particular pricing tier of card is available and pushes it as far as they can. So if they review a 960, they'll put it against an R9 380, since they paired up well (around the $200 price range). Lots of 970 vs 390 ($300), 980 vs 390x vs Fury ($425-$500), 980ti vs Fury X ($600-$650). The best parts of the reviews are the Apples to Apples comparisons, where they take the 2-4 cards being reviewed, take the best performers most taxing settings that still held playable speed and then force the other cards to run at those settings. Give a true comparison of how well the rest of the pack held up.
