Installed on Aorus Master X670e. Hassle-free installation and operation. The anti-sag kit that comes with it may look fake but does its job and is precisely measured for motherboards like mine (correct height from the motherboard and hole in the right spot for the ez-latch mechanism of the graphics card). Managing the card through the Gigabyte control center is easy, and adding the card to it is also straightforward. The build quality seems quite good. The card I received came with the new 12V-2x6 (H++) connector and not with the classic 12VHPWR (H+), although in no case does its consumption approach the nominal even of the old connector. The card connected to a 12VHPWR power supply without any issues, as the new 12V-2x6 connector is compatible with the previous standard. After registration with Gigabyte, the warranty was extended to 4 years, which is particularly significant for such an expensive card.
On the downside, nVidia still does not include an automatic driver update feature within the driver control panel, and one must download the new nVidia app to gain this capability, which is clearly inferior to AMD's equivalent implementation. Also, there are moments when the card's fans can be heard without the card doing anything or the computer being stressed, and with temperatures that do not justify such behavior. Given the size of the cooler on this card, this is frankly unacceptable.
I haven't tested it yet in any game or program that would stress it, so for now, I reserve my judgment on its performance, although I believe it will be difficult to stress it at 1440p @144Hz. At some point, I will revisit the performance topic when I have tested it enough. In any case, 5 stars, although I would like to give it 4.5.
---------------------------------------------
After a considerable amount of time and many tests, I can provide some details that, however, only pertain to my own system. In other systems, there may be some deviations from my conclusions/results.
The noise issue was fully addressed by switching the card's switch from the overclocking position to the silent position. The result was that the card became practically silent; even under intense stress, the noise is now extremely low, and the value of the exceptionally large cooler is finally evident.
The switch seems to only affect the fan profiles and nothing else, as there was no noticeable difference in performance. Any difference in performance was within statistical error. Only in cases of intense stress was there a very slight difference, and that was because the card reached the temperature that caused throttle down more quickly when the switch was in the silent position.
In my system, the temperature difference between overclocking and silent is ~4.6 degrees in idle state and ~4.2 degrees in load/stress state. The difference in the card's consumption (max Board power draw) is negligible at 316.1W (silent mode) - 317.8W (oc mode), which apparently only relates to the change in fan performance.
All tests were conducted at 1440p with the 566.36 drivers, and in no scenario did the card drop below 55 fps. The card was tested in dx11/dx12/Vulkan with high/ultra settings and without frame regeneration. The only problem I encountered was crashes in Baldur's Gate 3 with the Vulkan API.
