[SOLVED] What motherboard and cpu should I buy to upgrade my current?

[DekuMario]

I'm currently trying to upgrade my motherboard and cpu so I can improve the switch to pc gaming. The game I will be playing most of will be Destiny 2. I am already thinking of upgrading my graphics card from a gtx 660ti to a Radeon RX 580 8gb. My budget is around $300. My specs are:
CPU: AMD FX 6300 3.50 GHz
GPU: Nvidia GeForce GTX 660Ti
Motherboard: Asus M5A78L-M LX PLUS Micro ATX AM3+ Motherboard
8GB Memory

I would really appreciate the feedback!
