I'm building a pc for my cousin. He is nearly ten and i think he will be using the pc for school stuff and games like Minecraft and turbo dismount. While i think those games will run well. Would i be better buying a Athlon 760k or FX4300 to pair with my 7770 1GB which i have left over from upgrading my pc to an R9 280x. If you have any better CPU's to put with the 7770 please let me know.Thanks in advance.
