well, i am going to buy a gaming pc and wondered if a rx 570 would be enough, have a ryzen 3 2200g processor and 16 gb ram. i am probably gonna play with medium grafics, but i want to know if it will do.
That's a GPU much powerful than a GTX 1050 Ti, which is a decent budget gaming card. You should be fine running Beam on decent settings on decent framerates. Also, with an APU if you have some problems with the discrete graphics card you can use the APU to game as AMD's Ryzen APU is actually decent for light gaming. But if you could, you can get better CPUs down the line.
You should be fine. According to UserBenmark, it seems decent. https://gpu.userbenchmark.com/AMD-RX-570/Rating/3924
They update their drivers frequently, but the real problem is that they are slow to address serious rendering bugs in the Radeon drivers. From what I've read, Nvidia GeForce drivers have their own set of issues too though.
I don't think I am experiencing any of those issues with Nvidia, everything seems to just work and straight out of the box. Market share of AMD gaming grade graphics cards is so super small that it is only natural they will have less resources to address issues and especially if it affects only few games, why would they really bother, it is added cost which will cut profits and only way they can sell their GPUs are to keep prices so low that they don't really have much left for additional costs. As long as it works most of the time, it is fine, their small sales will not change from few games that will not work well. They probably are very keen to let developers to deal with their issues rather than fixing the stuff, it has worked in the past, why they would change that now? AMD GPU can be good value for money, but there is no way around the fact that it comes with higher chance of serious issues, it has always been so, even with Ati 9700 Pro and ever since, but also they are cheaper, so one has to choose what one wants. GPU prices overall are quite insane today, but sadly AMD is not one that can make much change to that, they are too small and make quite serious issues to their drivers, also it looks like they have given up high end GPU market completely, which would be wise choice from them as they can't make profit with those. As much as I would like to like AMD GPUs, how things are looking today, I really have to recommend to stay away, they are fine in datacenter use where some serious calculations are needed.
