ok, i was in imac 13,2 and graphics drivers were loaded properly, no qe/ci. downloaded mactracker and found out that my system is actually compatible for imac 13,1 so i changed the smbios and the result is it won't boot!
oh well, gonna download the 10.8.5 and see if that changes my luck for me tomorrow
EDIT:
reinstalled 10.8.4, smbios iMac31,1 since i cannot wait until tomorrow. edited AGPM as suggested above, i got QE/CI!!!
