Unlike the 2070 Super, RX 5700 XT has some specific models which are pretty good in terms of temps, and others are horrible. Both GPUs are very close in performance while 2070 Super being 5-15% faster on average while being much pricier. So it is upto you and your budget, as for me, a good 5700xt and a regular 2070S prices were the same, so even though I wanted to buy the first, I went with the latter. What models of both cards available at your place and what are their prices, kindly let us know.
