Either you don't have the latest (non-Beta) Drivers from AMD's website or your PSU is underpowered. Start by updating your drivers after a clean uninstall with reboots between each step.

Ensure the Graphics Card is sat firmly in its PCI-E x16 slot (not at an angle) and that all Power Connectors are securely attached to the card.

The R9 280X requires a minimum of a 600w PSU, and ideally something closer to 700w+. Some 600w PSUs might be underpowered as far as that card is concerned.

If you get the opportunity, test the Graphics Card in a different PC with a higher-powered PSU to make absolutely sure that's the cause, before splashing out on a new unit.

I had this exact same problem. My specs are a FX 8150, 8gb ddr3, and a r9 280x power color. I figured this would be great for gaming, but on BF4 I averaged like 40fps?!?! Not what charts shown. But I found the solution, its acutually isnt the GPU, its the CPU. The fix is EXTREMELY easy. Just go into your BIOS->Overclocking->CPU->CPU Features->HPC, and turn HPC ON. HPC will stop the processor from underclocking itself under easy loads. So when you go into a area of a Bf4 map and there are few people, it will underclock thinking it doesnt need to work, in turn giving you minimal performance. Hope this helps!
