I recently purchased a Gigabyte 970A-DS3P for use with my XFX R7770 Ultra OC. When using one card I get good performance. Windows rates my graphics at 7.7. When I added a second card and enabled crossfire I noted that my performance had dropped to 7.4.

Two factors I am dealing with: Number one, the second card is in a slower PCI-E slot (X4), I was not aware of the slower socket when I purchased the mainboard. Number two, I cannot get the card in the faster socket to display video, video will only display through the card in the slower slot. Can anyone help me?

--"windows says bullshit install catalyst and mantle you should be good"

I installed Catalyst but do not see any way to set the "Preference" to select the card in the faster slot as default. Any hints?
