There is graphics card to motherboard
Graphics card to power supply for need of pcie 6 or 8 power power, sufficient 12V amps for gpu, cpu, fans+motors, and total power
graphics card to computer case for physical size
You can get weakened performance by a low performance cpu with a high performance graphics cad
You have a PCIe x 16 slot so your motherboard is compatible to all modern desktop-tower graphics cards.
That RX 570 requires 1x8pin pcie power from the power supply.
A-series CPUs associated with that motherboard, or even the Athlons, are generally weak at gaming.
You cannot do much about it, but be aware the RX 570 may not live up to gaming performance reported with core i7's.
