So far I must say, this card is already impressing. I'm still on the Normal BIOS, being capped at 425-435W maximum limit, and I'm already hitting ~14.4k on Port Royal with pretty modest overclocks. My personal best is 14.7K on my old 3090 and that was no where near 24/7 stable either.
Given that that means I have another 100W almost in headroom once I switch to the 'normal' LN2 BIOS, I think this thing is going to be quite impressive overall.
Also, the temperatures on this thing are awesome, idling on the VRM/vRAM is in the 20sC(!!!), core is about the same as my 3090 Hybrid, unsurprisingly, and so far I haven't hit 50C load during PR testing, and the VRMs/vRAM is varying between ~45C-50C on the hotter ones & as low as 30C on the cooler ones. Crazy considering the same type of testing on the regular 3090 FTW3 Hybrid was seeing temps in the high 50s & 60sC on the same components with the lowest being in the 40s.
