Hai, I have GA 990fxa ud5 motherboard running with windows 8.1 and 2 sapphire readon hd 7770 over clock, gigahertz edition graphic cards cross fired for my games to play. Would there be any difference if i change it to single nvidia geforce gtx 980 graphic card. Please give in detail what could be the difference between 2 0f 7770 and 1 of gtx 980?
Thanks in advance
