Maybe it was this video. And true, there’s a pretty big difference between the cards. I just don’t like AMD display drivers (they’re overwrought with animations, take up way more memory than they should and crash frequently at least for me). Many games are optimized for nVidia on DX 11, but they don’t run meaningfully better. GTXs are cheaper than RXs now though.
I would need to double check, but I still think AMD wins in performance per dollar. That being said, NVIDIA 10 series cards are dropping in price…to about MSRP from what I’ve seen. Saw my exact 1060 card I bought like right when they came out for the same price I bought it at: $250.
Checked with current pricing, and the RX 560, 570, and 580 are better performance per dollar.
