WAOW Maziar, now you disapointed me. My MSI R5770 Hawk is a new one, i now look only for mobo and i hope this GPU is really good one. Maybe not a perfect but i hope that every game will be handle in max
And i not agree with you Maziar.Motherboard is a most important component in one computer. If you are motherboard is a poor (cheep) then all component on her will be with less circuit of power, and cant reach max.
oopps i edited my post,i didn't see you have a 5770 already.
About the motherboard i didn't mean motherboard isn't important i said "Its doesn't make a difference in gaming."
But ASUS P7P55D is a good choice go for it.
