hello, i have a gigabyte p55a-us3l motherboard and i5-750 at turbo mod to 3.2 GHz and i want to put another 5770 on my system. in my country, i asked some people that question, but they said:"your motherboard does support cf, but not full cf...."
what does it mean? that i can only do 2 way crossfire or something else?
please help me
Well we have 3 CrossFire modes,the first and the best mode is dual 16x,the second mode which performs close to dual 16x is dual 8x,and the last one which performs significantly worse compared to dual 8x/16x is 16x4x mode which is what your motherboard supports.
So your motherboard support CF but at 16x4x,which i don't recommend to choose if you want to use CrossFire because it won't perform very well compared to dual 8x/16x.
