Here is my little brother's computer stats

First gen core i7
EVGA tri-sli X58 ATX mobo w/ triple channeled RAM
12gb DDR3 Ram @ 1333mhz
2 Sapphire Radeon HD 7770`s
Zalman 1100W PSU
Antec 1200 Case
2 1080p monitors


We just got titanfall and when we run his cards in crossfire the game runs like crap, I don't know what the deal is, all of his other games run just fine when the cards are in crossfire, but not titanfall. The game actually runs better when the cards are not in crossfire on titanfall.... anybody know how to remedy this situation? I was the one that built his computer for him and want him to get the most out of it. The weird thing is that the 7770 we bought a year ago has a slot for the crossfire bridge, but the one that we bought about 3 weeks ago does not. I called AMD and they said I didn't need one, I guess not cause we can still turn crossfire on in catalyst

and besides, if that tri-sli mobo didn't work with crossfire I wouldn't be able to crossfire the cards on other games, which I am able to do
