The only reason is if your PSU doesn't have a six pin or any spare power (that you can use an adapter with) that you need for the 570. To anyone gaming at 1080p or less I would recommend the 570 - it can pretty much play anything at high settings at 1080p. I was very impressed with how good it was for the price and I am saying this with a 1080Ti in my main rig.RX560 - increased price for old tech?!? Is this the 'trade war' or what? Why would I buy the 560 when the 570 is just a lousy ten spot more?
