Just installed my second 5870 and put them both in crossfire.

I have the HIS HD 5870 iCoolerV in the top PCIe x16 slot and the XFX card that I JUST bought (another HD 5870 with the same amount of RAM) in the PCIe x16 slot underneath.

They are connected together with a bridge and Crossfire is enabled. Anyway, I ran a benchmark on the single XFX Radeon HD 5870 by itself and got a 3dmark06 score of 19000 something. I then ran the test again (but this time with the HIS HD 5870 WITH the XFX HD 5870 in crossfire) and got a result of 19,000 something.

So almost exactly the same. Other than plug both cards in, reinstall graphics drivers and enable CrossfireX in the cataylst control center...I havent done anything to either of the cards.

Really disappointed. : ( help ?

However...bad company 2 still has some lag. The same with black ops. Quite a lot objects are still loading in front of me when I'm running towards them. Is this usual ?

It's ticked in catalyst control center so I believe so, yes.
