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...."

Hello
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.

well, i already have it on my system,so i cant afford changes right now.
but the x4 will give something like 30% more fps in games when the x16 cf can give up to 80%???

x16 and x8 are pretty much the same(unless on extremely high resolutions) and will perform approximately 40-80% better than x16x4(Depending on the game and settings)

Well a single 5770 can handle BC2 on 1680x1050,there is no need to CrossFire unless you play at 1920x1200 or higher.
