I’ve created a small tool to quickly compare GPUs that I use when I browse second hand offers.
It only uses one game (The Witcher 3, 1080p), but it’s enough for me to quickly know if it’s worth investing more time looking into it.
Compared to your 6950XT:
9070 XT : 20% faster
RTX 5080 : 49.12% faster
RTX 5090 : 69.47% faster
