I don't know if I should upgrade if I can or start over with a custom. If I should start over, can you provide a part list to go from with a $500 budget. I would like to play Overwatch and League of Legends with this. Thank you for reading this.

Build a new machine. No way you'd want to bother from upgrading from an APU.
This should cover your needs. Unless... You also want another keyboard and mice. Do you?

Thank you so much for the quick response! I do not need another keyboard and mouse, but I will need a wireless network adapter because I don't have access to ethernet. Also, is it hard to build a PC. I am 16 and I do not know the difficulty of building one.

At least... Good thing is, the wireless card is based on AR9285. Awesome little thing, if you don't mind the lack of 802.11ac.

similar to okcnaline's build. Slightly over budget, I went with a less power supply, case, motherboard and Ram, I saved enough for a 128 GB SSD, for your OS and most used programs. Like ocknaline, I suggest reusing your 1TB drive. the PSU is NOT top quality, but I'm also sure it won't just up and die on you either, especially with the low load this build produces (just 212W)
