How would this build preform?

I have set-up a budget build for a gaming pc, not too intense gaming though. Hopefully I can get decent fps on medium settings. If anybody knows how this will preform please tell me. This is my first build and I hope it is ok.

Case Built In Vantage Blue Gaming Case with LED Fans

Motherboard Gigabyte 78LMT-USB3

CPU AMD FX 6300 Six Core

Memory 8gb crucial DDR3 1600mhz Performance Ram

Hard Drive Size 1tb Seagate Barracuda Sata 6Gb/s 64mb Cache 7200rpm

Optical Drive Samsung 24x SH-224DB/BEBE Sata DVD Writer

Graphics Card AMD Radeon R9 280X 3gb 

PSU Size Corsair CX600 80 Plus Bronze 600w Power Supply

Operating System Windows 8.1 64bit With License / Disc Installed and Ready to go

I got this build for £565 

for 1080P, this build will play most games on Ultra, with some of the newer games needing to be put down to high.

Perform like a space heater thats about to burn out in a short amount of time.:)~ You might be okay at stock clocks, maybe?

I already have an aftermarket cooler :D I've forgot the name but it costed £30

And my case has 4 fans if that helps.

Don't overclock and you should be fine.
