Question about MSI Radeon RX 570 ARMOR

Yes.
Yes.
Yes.

PS: Of course, it always depends on what kind of games you want to play with it, at what resolution, with what graphics settings and what FPS.

so the 570 can easily be built into a 530 gaming pc, has about the performance of a 1060 3gb with massive oc or a 1060 6gb with poor cooling....
