So, I built my PC a good while back and I don't know if/what is wrong. I get very low fps in games people with much worse rigs (or so I think) easily climb towards the 100's

My build
•MSI A88X-G45 Gaming motherboard
•AMD A10-7850K apu (I believe it is an apu although Idk the difference)
•MSI NIVIDIA GeForce GTX 960
•2x4GB sticks of Corsair DDR3 @ 1,340MHz
•256 GB Samsung SSD
•1TB Western Digital disk drive @7,200RPM
•750w Corsair power supply
•running Windows 10 64-bit

I built it my self with very little knowledge of PC building and it's very possible I got terrible parts. if so, a replacement part suggestion would be nice. If anyone can see a obvious mistake or can help me figure out what's wrong I would greatly appreciate it.
Thank you in advance for any help.

I ran BF4 and Afterburner said my gpu was either high 90's or maxed the whole time
