im running on 10.5.6 and i have gigabyte's GA-EP45-DS3L and using kallyway . i've built the system for using with logic , and i've got everything running smoothly at the moment , all the plugins for logic etc . i want to upgrade the motherboard of the system , would it be ok if i just change the board and install the kexts required ? or will i have to go through all the process of installing new os ? ep45 is a super compatible board , didnt have any issues installing . are there any board recommendations for intel775/16gb ram capacity ?
