as far as multithreading goes Why would nehalem be better at it? isnt with multithreading that each core is split in half? and lots of synth NEED a full core while playing instead of switching between them.
im talking third party apps, cubase isnt well known for great builtins anyway.
Are you referring specifically to Cubase? As I understand it, Nehalem isn't the issue. Supposedly better multi core scaling is going to be included in future updates within the version 5 cycle.
I'm not holding my breath, but here's hoping....
