Two Graphics Questions

[DarkDwarf]

Hey everyone,

I just built a new computer with three graphics cards in it. 2x Radeon HD 4870 and 1x Radeon 9280 (0r 9250... 92XX generation). The 92XX card is older and I have had it for some time. I plan to use dual monitors while gaming, so that I can run Crossfire while playing Crysis for example and look at a walkthrough or have my gmail open on the other monitor. I planned to use the bad GFX card for this.

However, when I actually install the GFX card, the computer will boot, but will not display anything on the screen. How can I make this work?

Second question: crossfire. How do I know it is enabled and working? I know the "Enable Crossfire" box is checked, but I am unsure whether or not Crossfire is actually enabled. How can I make sure it is picking up both my cards and putting them in Crossfire?

Any help with either of these problems is greatly appreciated!

Update: GRID seems to crash. I don't know what the problem is. It drops to an FPS of about 1 (estimated), and then crashes several seconds later: This is on "Ultra" settings. It ought not to crash, especially since it shipped with the cards. And since I have two of them, I would expect to be running at Ultra Ultra settings. The cards? are idling at 45 with fans at 50%. Installing 8.7 as I type this.

Try disabling crossfire when playing Grid.

Nope, no luck. It runs great for the first five seconds of the race (which it was not doing previously), then jumps from 4-5fps to 40fps back to 4-5fps and stays there.

If the old GFX card idea fails, I'd at least like to be able to switch from CF to dual monitor. Do I need to have both monitor cables on the same card for this?
