Hello,

A few days ago, I bought an old computer, with a 4850. I already had a 4850, so I wanted to tun it into crossfire.
Now to make a long story short, there isn't any game that has a performance increase. Even worse: GTA 5 is even stuttering more with crossfire than without.
If I look in afterburner when running GTA 5: GPU1 usage: ~40%, GPU2 usage: Going up and down like hell from 100% to 0%
How can I get GTA 5 to run properly?

----
System specs:
CPU: i7 920 @ 4,2.
MB: Rampage 2 Gene.
OS: Windows 7, 64 Bits.
GPUs: 4850 Crossfire.
If you need to know more, let me know!

The power supply is a bequiet purepower 530w. That can't be the problem. I know sure that both cards are working as they should, I tested them both. There is a new bios update available, I will try that, but the last time I installed it my system became unstable. But I will try later today. Thanks for your answer BTW.
