Getting back on topic though, whats peoples opinions about the 3900 XT
Only paranoid negativity.
It's still a 12 core, dual CCX, dual chiplet design so it's going to have all the "shortcomings" of the existing 3900X, and I'm not sure the clock bumps will make that much of a difference against the niche use cases Intel still retain their lead in. As a result, enthusiasts will go "cool, nice to see TSMC's yields mature nicely so we can get this bump", the Intel sheep will go "lololol AMD do a refresh and STILL can't get 5GHz and beat us at gaming, which is the only thing that matters. Faildozer 2", and the casuals will go "there's an XT now?".
So I kinda see it as pointless, tbh.
And putting in some refreshes potentially doesn't bode well for Zen 3 landing on time, even with the Human Malware running about. OK, so Comet Lake is out, but who really cares? Those extreme FPS gamers will still buy Intel because it's the best for their purposes, the fanbois will still cry idiocy, and the non-partisan enthusiasts have dismissed it already. It's a detriment to AMD to do this refresh as it's going to be seen (whether intended or not) as a response to Comet Lake, and it's a response which likely won't address the deficits. Zen 3 is taking on Rocket Lake, so I'm not sure what can get served by AMD even acknowledging Comet Lake's presence.
Unless these clock bumps really do **** Comet Lake, pushing AMD in front before Zen 3 even lands.
