I don't know why moderators are deleting my comment but here we go again:
Unfortunately, no. The card still have all kinds of issues related to power saving mode (pc reboots when display goes into power saving mode, can't wake from sleep, black screens, driver timeouts etc.) These are specific issues from 6600xt. There is also issues from RDNA 2 architecture itself (stutters and micro freezes on light load GPU games because of deep sleep state)
AMD doesn't even reckognize those as known issues (avoiding a class suit maybe?) and keep themselves in silence just like they are doing with Ryzen 5000 chronic WHEA 18 error and usb connectivity issues on some motherboards chipsets.
Stay sway if you can and buy a NVIDIA equivalent. Or wait for Intel GPUs.
