Are there any drawbacks to AMD GPU's? I do want to upgrade and can probably sell my 1060 to a friend who wants to build a PC.
and on that note, have any of you all used Kinguin's suspiciously cheap windows 10 keys?
Right now the only real drawback from the RX 5700 XT etc is that the temps are kind of high (still safe and within limits) and the card is somewhat loud. But that is only because of the blower fan design on the default card. Very soon 3rd party companies will release their own version of the RX 5700 with dual fans/triple fans and much better heatsinks etc for the cooling solution which will also make the card much quieter. The 3rd party cards will also be overclocked etc right out of the box so they will be better then the default cards. But that being said the default cards are still very good gpu's.
I would personally buy a RX 5700 XT over a RTX 2070 Super because the performance is almost identical and the card is $100 cheaper. And its important to note that the RX 5700's have been out for just a few days now and as drivers update etc the cards will become even better/faster then they are today.
And I highly recommend going with a Sapphire brand variant for any AMD GPU as they are widely regarded as the best AMD GPU vendor and they always maximize performance and stability.
As far as Kinguin goes i have heard mixed things but mostly that the windows keys work just fine. They also offer buyer protection that pretty much guarantees you get what you pay for or your money back etc. I plan to buy one of their windows keys myself here soon, but honestly you do not really even NEED to buy a key. My watermark doesn't even show half the time and when it does i dont even see it anymore.
