Ok so I had to get another motherboard as the one i had died on me, EVGA replaced it.  I went from a P55 Classified 200 to a Z68 FTW.  I have two XFX 6970's in crossfire.  I have 3 screens in eyefinity mode. When I run a game, no matter what it is on a single screen i get awesome performance.  Example, guild wars 2 i get 70 to 250 fps.  When I try to run any game in the full resolution of 5760X1080 i get god awful fps.  I get graphcis glitches and some artifacting.  With a single card in eyefinity mode, performance is awesome i get good fps and no graphics issues at all.  What could cause this issue?  Only when crossfire is enabled and in eyefinity mode all games suffer worse fps than with a single card!  With the single screen crossfire works perfect.
