MSI debuts slot-powered Radeon RX 560 Aero ITX OC cards
 

If the Radeon RX 570 and RX 580 cards are too much for your build, but the RX 550 is too little, perhaps the RX 560 is just right. AMD's refreshed Polaris chip is showing up aboard more cards like MSI's Radeon RX 560 Aero ITX OC. The card comes in flavors with 2GB or 4GB of GDDR5 memory running at 7 GT/sec.
