Upgrading to Asus P8z77 mobo but which one?

n yes i had a office desk top with n i 3 , socket 1156 !!! lingering around , busted , i sent the Asus M/board 4 warranty , they replaced it instantly , n turned out , it was the 1st gen i 3 Intel that went bust , got that replaced as well, diagnostics were wrong only 4 the reason 1156 sockets r not very popular around here , even the dist didn’t have n i3 around 2 verify the exact fault… main point Asus is a gr8 rugged M/ board… sm
