Thanks, my father doesn't want a quad core or dual core hyperthreated, he wants a phisycal dual core with 8gigs of ram. Btw is there any chance this AMD CPU won't work well with Avid Pro Tools?
I am not very familiar with that software honestly but there is no hardware reason that CPU shouldn't work. based on this site though:

It will be fairly under powered for the task and take some time to complete.
Why does your father not want quad core or hyper threading? an older dual core is a strange request for such a high end piece of software.
If it must be that this would be the best CPU that meets those requirements.
