Which GPU should I choose: RTX 3060 Ti or RX 6600 XT?

You should definitely go with the RTX 3060 Ti! It offers much better performance and has the advantage of DLSS for better frame rates in games. Even though it's $40 more, I think it's worth the investment in the long run.

If you're really tight on budget, the RX 6600 XT is cheaper, but I'd be hesitant due to the lack of future support. The 3060 Ti, while more expensive, could serve you better in the long haul.

Yeah, the 3060 Ti is the way to go! It may cost more now, but the performance boost and features like DLSS will definitely pay off. I've seen models go for around $200, which is reasonable considering how well it performs.

I'd suggest avoiding the RX 6600 XT if you can. AMD's 6000 series is kind of in maintenance mode, and there's a lot of uncertainty about support going forward. Investing in a better-supported GPU like the 3060 Ti makes more sense to me.
