I have radeon 7990. And how can i know is it works fine? Using msi afterburner it says that in game that first gpu works something like 50% (it is different every second), second gpu works 99% in game and the number isn`t changing. After leaving a game it`s always 0%. Is it normal? About fps. Bf4 4 multiplayer(maxed out 1080p) 60-120 fps. Metro last light ssaa x2 no physx 60-70fps. With physx and 4x ssaa it`s 25-30 fps. IS it normal?In gpuz first gpu has Bus width 384 Bit and Bandwidth 288.0 Gb\s. Second gpu has bus width 32 Bit and Bandwidth 24.0 Gb\s

We'll need some more info as performance depends on your system, cooling and where you plugged the card into. If your card is not in the top slot it will not have as much bandwidth to play with.

What's your cpu usage like? For that matter, what's the rest of your specs?

I have 7002 Psu (High Power EP-700 BR), Intel core i5 3350(didn`t see usage), card is in PCI 3.0 slot. I really want to know why second gpu is always 0% and in game always 99%

Can`t find how to on or off it, but when i am in the game it is crossfire logo in the right corner of screen. In CCC i enabled Crossfire for apps without profile.
And when i am clicking on CCC in the right down corner in windows i see 6 GPU (AMD Radeon HD 7900 Series) Is it ok?
