Seen some really good benchmarks from the Radeon 6800s. But I've also seen some scary stories of drivers not working worth a shit, and performance close to the GeForce cards with half the RAM. The Radeon card apparently suck at ray tracing right now too.
AMD RX 6800 XT runs at almost half the frame rate of Nvidia's RTX 3080 in Vulkan Ray Tracing tests
Still too early for me to jump on the Radeon wagon considering the prices they're asking.
