The amd 780G chipset supports mixed crossfire? I mean.... Could I mixed a 4830 and a 4870 in crossfire? The motherboard is: ASRock A780GXE/128M. Does it support two 4830 in crossfire or a 4870 and a 4830?
most people but both of the same card in through for performace, if i also remeber crossfire was the first to bring out 2+1 2 for rendering and 1 for phyics but the third don't have to be the same, for example two HD4870 and one x800 for the physics
If I were you I would NOT run the HD4870and HD4830 together because of different memory speeds on them.... 1.8ghz vs 3.6ghz (Or is it the base speed that matters... because in that case- they are both 900mhz)
