Hi, I was thinking of buying the RX 570 8GB, but is it like the AMD FX where it looks really good but it is slow? If not, should I get Nvedia's new GeForce GTX 1660? If not those to cards, I am on a low budget, so which one should I buy? I want to play on medium-high settings at a smooth FPS rate. Also, I cannot run SLI or Crossfire because my motherboard (MSI A320M Pro-vh Plus) only has 1x PCI-E x16 slot. Thank you for your time!
