I bought two MSI Radeon HD 7850 2GBs half month ago, and I was excited that my games run better now than with my old 6850, then today I tried the games I have been playing with only one card.... I got the same amount of FPS.
Only two differences were Trine 2 on Extreme and Bioshock: Infinite on Ultra, they run way smoothly on 2 cards... But all other games its the same performance either with one card or two cards. Is this just how Crossfire is, or is the lag coming somewhere else? Like I saw in World of Warcraft the same amount of FPS, but thats CPU intensive game right?

My specs:

Asus P8Z77-V LK MoBo
Intel i5 3570k @ 4.2Ghz
RipJaws 1600 2x4Gb
Seagate Barracuda HDD 64Mb cache
2x MSI Radeon HD 7850 2GB OC Edition
Chieftec 750W PSU (Crossfire/SLI Certified)

CPU usage is jumping around 50-80% and GPU1 usage is 99% and second is about 50% depending on situations... and I have the nonbeta Catalyst... the 13.9 one, is that bad?

Update: During Guild Wars 2 my CPU usage was only about 40%
