I'm deciding between a used RTX 2080 Ti with 11GB of VRAM and an RX 6600 with 8GB. The 2080 Ti is roughly 25–35% faster in traditional gaming, supports DLSS, and offers more VRAM, but it is an older 2018 flagship that can draw over 250W. The RX 6600 is newer, much more efficient at around 132W, and should run cooler with less concern about worn fans or thermal pads. My main target is 1080p gaming, though I may consider 1440p or VR later. Is the extra performance and VRAM of the 2080 Ti worth the higher power use and risk of buying an older used card, or would the RX 6600 be the safer choice?

The best choice depends heavily on the prices and condition of the cards. A healthy 2080 Ti offers substantially more performance, but a heavily used model can need maintenance. A newer RX 6600 is the safer, cooler option, while alternatives such as a used RTX 3060 Ti or RTX 3060 12GB may also be worth checking if they are priced competitively.
The older-card driver concern is less important than the physical condition of the specific 2080 Ti. Drivers are generally not a reason to reject it, but you should inspect temperatures, fan noise, and stability before buying. For 1080p, either card can work; the 2080 Ti simply gives you more headroom.
The RTX 2080 Ti is the clear performance winner, with more VRAM, DLSS, and better results at 1440p or in VR. Its power draw can be reduced with an undervolt, often bringing it below 200W. If you choose the used card, check its condition carefully and make sure your power supply is adequate; a repaste or fresh thermal pads may also help.
For straightforward 1080p gaming, the RX 6600 is usually enough and has major advantages in efficiency, heat, and age. It makes more sense if you value low power consumption and reliability over maximum frame rates. At 1440p, however, the 2080 Ti’s extra performance and VRAM become much more useful.
