Yes, 9070 XT is... kind of stretching this nearly 10 year old CPU a little considering it's meant to be roughly 7900 XTX-tier, especially for people like me with paired CPUs, but it's also 2.0-slot and is guaranteed not to be $1,500 used or $3,000 new like the Radeon Pro W7800 is. Plus, it can always move on to the next generation when Raptor puts out the S1-based boards. I think it'll be my next move after the RX 570... I'd almost certainly need to get a stouter PSU than 550 W though, even that's cutting it close when I got a 231 (to be fair, it was a really good price).
Hopefully, RDNA 4 is similar enough to 3 that compatibility is pretty much already taken care of even before it's out, I know AMD has been doing some kernel work recently regarding it on AMD64.
