Crossfiring

Hi this is my set up.

GA-Z68XP-UD3 Mobo
Intel i5 2500K
8 Gig DDR3 Ram
1TB HDD
2x XFX Radeon 6870 in Crossfire mode

My question if anyone can help is this.

After I crossfired I started lagging in my games a bit. Like there was video lag. I was getting 60FPS in MW3 and BF3 on high settings.

After I took out the second card I noticed a small difference in lag. Still got 60FPS.

Have I got something set up incorrectly?

When I activated Crossfire in the CCC it briefly noted "2x GPU X4"

The mobo should support 2x 8 mode?

Am I doing something wrong?

Is it not worth crossfiring as I am thinking of selling the second card if not.
