Hey guys, new to the site. I just bought another 4890 to CF in my computer. I just wanted to know how I can tell if they're working properly? Yes, they are both showing up in device manager and appear to be working and I have deleted old drivers and downloaded new ones. I wanted to be able to get more fps on Battlefield Bad Company 2. I just want to make sure I'm getting all I can with what I've got. Btw, is 750W Corsair enough wattage? Thanks in advance...

750 W is plenty

go to catalyst control center and there should be something indicating a crossfire setup

Your PSU is fine
Dont worry about that.

Go to CCC (Catalyst Control Centre)
See for CrossFire tab, and see if CrossFire is enabled or not.

It is CF is enabled but it doesn't appear I'm getting more FPS on Battlefield Bad Company 2. I've got everything Maxed with the Res set at 1920x1080 and I'm pulling around 50. Is that all I should expect or should I be getting more than that? I know with just the single card I was getting 100 fps on BF2 and it's still the same with 2 cards. Any help or advice? Thanks guys..

There are certain games in which CrossFire barely help to increase fps, because they are mostly CPU bounded.
e.g. FarCry2
