I remember that I replaced my 7870 back in 2016 when it was feeling a bit underpowered for 1080p gaming. I replaced it with a GTX 980, which is about the same performance level as a 1060 6 GB/RX 480/RX 570. Trying to game with something slower than the 7870 now would be... a challenge if it goes beyond 2D or retro gaming!
