When I built and installed my system about a year ago all the how-tos were saying to use standard pc. However, I am now experiencing stutter audio and clicking when running Nuendo. I have been told by some to switch to ACPI that it is a better bet. I habe been told by others that my board is older and to not screw with ACPI. Any thoughts pro/con the ACPI? Is there anyway to convert? Or do I need to reinstall? When I reinstall do I need to blow away & recreate all partitions or just the partition with the os on it? Also, any things to check for the stutter audio?
