The high multi-monitor power draw issue affected RDNA2 for some in early driver releases but they managed to iron it out so I expect the same here.

It's a known issue for sure atm on RDNA3.
Crashes in Witcher with those settings, so it’s probably just the game?
Prior to the crash the junction temp was around 65’c

Probably means too few voltage. Try memory at 2650 and GPU voltage at 1075 and retest.
The VRAM does not always downclock on 6900xt with multi displays, most drivers are ok though, not had it in 4-5 updates.

Cool, keep testing. Can always try bumping the memory up another 25-50Mhz.

Yeah, I still have the issue depending on the refresh rate of my screens, but I rarely have the second switched on sonl it's not a big problem. Also had the same thing intermittently with my 1080 Ti on certain drivers.

Stick FSR 2 on perf and you should be good. Witcher with RT gets massively CPU bottlenecked in places though so if in cities/towns it drops below 60 don't be surprised, GPU use will drop and one/two CPU cores will get maxed. Seems to be a game bug where it isn't distributing the cpu load over all the cores like cyberpunk does etc.
Doubtful - personally I would wait and see what the new x3d parts are like, they should bring tangible benefits.

Yes, 100% yes. Warzone loves 3DVCache, I say this as a person who had a 5800X3D on Warzone with a 6900 XT and later a 6950 XT. If you get a 5800X3D, a 6900 XT/6950 XT would be a perfect match.
Just read the comments.
EDIT - Let me edit my post slightly as I didn't realise you were already on 5800X3D.
Swapping to AM5 from (AM4) 3DVCache would only be worth it if you swap to a Ryzen 7000 series that features VCache. Then it will be worth it! @Kali81

Unreal Tournament 3 at 4k, 400fps! Skyrim at a constant 60fps without having to turn ENB settings down! I can actually run Quake 2 RTX now!
Some coil whine at high frame rates, but far from the worst I've heard.
High idle power. From the recent driver release notes I was hoping a workaround would be to set the refresh rate to 60Hz for both monitors, but unfortunately it only goes down if I both set the refresh rate to 60Hz and disable Windows HDR. Hopefully it won't take too long for AMD to fix it.
I checked immediately after installing the card and it said 3140MHz. I checked again before posting this, and it now says 3080MHz.

Oof, 3140Mhz, that’s higher than mine which also varies but peaks at 3105Mhz.

Has anyone tried Red Dead Redemption 2 with the 7900 XTX? Game runs insanely fast and is beating my 4090 at 4K max settings (MSAA off).
This makes me a happy..

Me too. One game I’m going to play through again with this card.This makes me a happy..
