Hi, after installing my second r9 290 I noticed that my gpu usage had gone down. Usually it's 50% for both cards. Except for one game, sniper elite v2 which uses both my gpu's to the max all the time.

Other games like bf4, crysis 3 and bf3 only uses my gpu's 50% each.
(It averages between 40-60%.)

I'm using a non overclocked fx-8350 and my maxium power usage was just over 700w. Any suggestions to what might be bottlenecking? I can clearly see that my framerates are fairly low compared to other benchmarks. I got around 7000 points in 3dmark firestrike extreme as a total score.

Specs:
FX-8350 @4GHZ
GA-990FXA-UD3 rev 1.2
Corsair vengeance 8gb @1600mhz
R9 290 windforce (Gigabyte)
R9 290 tri-x (Sapphire)
XFX Proseries xxx edition 850w 80+ bronze.
Fractal design define R4

Crossfire is enabled in catalyst control center and I can see the crossfire logo in games. Both my cards are synced at the same clock speeds. Core: 1000mhz Ram: 1300mhz Also my temperatures are good. both my gpu's are below the 80's and my cpu is averaging 50c with stock cooler right now on load.

Any suggestions towards what might be bottlenecking?

My first thought is CPU
FX8350 isn't an overly strong gaming CPU and not overclocked only magnifies it. I'd try an OC on your CPU and see what it does for your FPS/benches. A noticeable increase would confirm.
