Bought this card a few days ago. The value of the US dollar is quite low these days (3.60 PLN instead of 4.15 PLN back in January), which has dropped prices of most electronics in Poland. I paid about $780 + VAT, but in Polish currency it was 3449 PLN. You couldn't really buy even the cheapest models below 4100 PLN around launch (MSRP was and still is 3899 PLN).
Started playing around with undervolting right away. Currently I'm at 2700 MHz @ 0.85 V. In Expedition 33 I'm getting 65-85% GPU usage with 130-180 W power usage (capped 60 FPS), so I'm happy with that.
In less demanding games like Motorfest or Valhalla I can do native 4K60 now instead of 1620p, with similar headroom left.
Efficiency is similar to my 4070, so ~50% more performance results in roughly ~50% more power. Uncapped benchmarks can peak at 230-250 W (4070 would peak around 160 W), but actual gaming at 60 FPS is mostly under 200 W. I'll definitely use more conservative settings during the summer, will probably push the card more between October and May.
Idle wattage is rather high (over 20 W), and very high during video playback - can go over 40 W watching YouTube/Twitch, and even over 50 W when upscaling SD videos to 4K with madVR.
I noticed different boosting behavior compared to previous generations. You can't really lock it to a single frequency even if the curve is flat, the clock will always jump around 10-50 MHz lower (so 2650-2690 in my case). And it used to jump in increments of 15 MHz, now it's 7-8 MHz.
The card also doesn't seem to like voltages lower than 0.85 V under heavy load. Even if I set the curve to 2500 @ 0.8 V, the voltage will still often jump to 0.83-0.85 V, so it's better to just lock it to 0.85 V with a higher clock for the strongest undervolt.
The fan profile is rather aggressive, trying to keep the card around 60 degrees. Setting a custom curve drastically reduces fan speed while keeping temps under 70 degrees (around just 200 W, though).
Fan stop behavior is also different. Fans seem to start up around 51-52 degrees instead of 60 on my 4070 Ventus. They also won't stop spinning during load even if the temperature drops to ~40. A bit weird. Custom fan curve doesn't seem to affect the fan stop threshold.
I have a GT 1030 to use for 32-bit PhysX games and it works nicely. Not sure what will happen when they remove driver support for Pascal, though. In theory you can install an older driver for the second GPU via device manager, but I don't know if PhysX will work that way. I guess we'll see.
Overall I'm definitely happy with the card so far. I paid 3199 PLN for the 4070 in April 2023 (which had a much lower MSRP of $600, but the US dollar was at 4.60 PLN back then), so taking inflation into account, this card is a much better product at 3449 PLN.
On a side note, this is only my second ever "Ti" GPU. I had the GF3 Ti200 for a while like 20 years ago, but since they brought it back with the Fermi refresh, I always had a regular model (with the 2070 Super being the only exception).
