Out of the box clocks are quite a bit better than my original. Just bumping up the power/temp and voltage limit to max and it goes over 2820MHz on the core in my test bed, High on Life (finished it up on the 3090 Ti while I waited). The old one was in the 2600 range and only hit mid to low 2700 when adding a stable OC.
Popped a quick and dirty +150 +1000 OC and it almost hits 3GHz.... sheesh!
And no Dolby Atmos issues so far (it'll take a few days to be 100% certain, since the old card it was quite intermittent).
