XFire with this card is just amazing. Will have to wait and see what future update/fixes and driver releases will accomplish for the new AMD cards. Hoping they will give nVidia some competition this time.

Lots of things that dont make sence in those graphs. Why would normal his cf beat the oc his cf 7970. And why does vtx3d and pcs 7970 oc beat the his in xfire?
