It's not a good card. Much better is a 2Gb Radeon r7 260x on Ebay or ebay.co.uk
The fx6300 automatically overclocks any core that reaches 100%. DX12 & Vulkan games will make better use of 6 cores than DX11. So the processor will last for a long while if you game and much longer if you don't.
On YouTube you can find many videos of the fx6300 performing fine in DX11 games. This video shows that the fx6300 can play Assassins Creed Syndicate at 1080p very well and no core gets near 100% which is sometimes the case when gaming on an Intel i3/i5
