My latest mistake has arrived.
To my surprise, and despite the seller specifically saying otherwise, it came in its original retail box.
This card is an absolute unit. It's freaking huge and freaking heavy.
Fortunately, it fits in my system just fine. I was slightly worried that my 10GbE NIC would interfere with it, but as you can see, that isn't a problem at all.
I ran a second PCIe power cable from my PSU because I know this is a power-hungry card. Probably isn't necessary, but whatever.
It performs almost twice as well as my 5700 XT in benchmarks. It seems to stay in the high 60s under normal loads and gets into the 70s when pushed. I'm using the "quiet" BIOS.
I only have two real complaints about it. As far as I can tell, the lights can't be turned off. Also, this card has insane coil whine when being pushed to its limit.
I might actually be able to play Cyberpunk 2077 now at a reasonable framerate...
