Good GPU but games are not acting right, what's wrong?

So I built my computer in July, it the very first one I built (its AMD based). Any first off here are my specs. ( Also sorry if this is not in the right section of the forums I wasn't sure where this would fall)
GPU: Gigabyte Radeon HD 7970
CPU: AMD FX- 6350 (with Hyper 212 Evo cooling)
RAM: 16 GB 2000 MHz DDR3 Ripjaw memory
SSD: Samsung 218 GB SSD
HDD: 1 TB x 3 WD Blue HDD
PS : Corsair 750x
MoBo: 990 FXA UD3
OS: Windows 8.1 64 Bit Pro Preview


Anyway, so I built my computer and I was not playing any games that were not graphically intense such as Combat Arms, Maplestory, and Team Fortress 2 and I was getting to the FPS cap or in Combat Arms (no frame rate cap in this game) around 190-500 FPS, (also i played in max settings on all those 3 games). However then I started to play Planetside 2 and Arma 2 (DayZ), and I was only getting 10-20 FPS at very low settings. Then I see videos of people using a Radeon 7870, or some other card that is not as good as mine, getting 50-70 FPS. I have Directx 11, my drivers are up to date, and I think i have all necessary software. Do I need DirectX 11.2 since I am in the Evaluation copy of Windows 8.1, does it have something to do with my CPU, or is it something else? (My GPU is running at 47 Celcius

Don't know much about your OS but CPU might be should be ok but ur mobo is PCIE 2.0 so that might be it, I'm not really sure.

Upgrade your drivers?

Also, check the temperatures of your GPU while under load, it is possible you have a cooling issue.

PCIe 3.0 cards are backwards compatable with PCIe 2.0, and I don't think a single 7970 will not fully utilize the bandwidth of a PCIe 2.0 x16 slot.
