I'm running Sonar on a MacPro via Bootcamp...
Excellent performance... If I'm right, when you do this, you are not running a virtual environment, only a virtual system bios which is stored on the motherboard for windows, but stored on the hard drive for a mac... So bootcamp virtualizes the are where this data is stored and feeds it to a full install of Windows...
The only thing I've found a bit tedious but far from earth shattering is that i can't open my optical drives from the keyboard as Macs do... And they hide the button on drive front so i must open the drive from the inspector menu in windows explorer... Not much pain... Its supposed to have been remapped as i set it to do so but it's never worked...
Other than that i often forget I'm on a Mac as I only use it for Windows/Sonar anyway! ;-)
I'm guessing that if you can do editing with a bunch of plugins etc., you can probably do the recording just make sure to use a separate hard drive for the audio... As far as Sonar knows, it has very little system needs to simply stream audiio... I've even managed to do some festival style events running 16tracks to an external USB2 hard drive!

BTW... I forgot to mention that I've heard a number of people have issues with running bootcamp as a partition shared with the Mac OS... I use a separate drive for my windows boot drive and a third drive for my audio drive...
