I currently have a Sapphire 7770 and I am not getting the performance I would like out of it. So I was thinking I could crossfire it or wait a while and get a 7950. So use wise I am getting 3 monitors in the near future so eyefinity with performance is a huge factor. So I need to know if the 7770 crossfire would scale up to it for the 200$ less Id spend on it?
