i just put in another graphics card for crossfiring and when i go to trixx is shows it is running at x1. my motherboard is a m5a99fx pro r2.0 and it should be running at x16. I did the very scientific test of running fraps and bf4 and had little to no improvement.

cpu- fx-6300
mobo-m5a99fx
gpu- r9 270x sapphire vaporx
gpu- r9 270x gigabyte windforce

now my first card is at x16 2.0 and the second one is running at x16 1.1. also the card running at x16 1.1 has a slightly lower bios version. would that make a difference. version 015.041.000.000.000000 vs 015.039.000.001.000000
