I'd just be using it for audio work. The dual GPUs are just for graphics aren't they? They probably don't boost speed for audio apps. If that's the case then I'd be paying quite a bit for something I'd never really use. Maybe just keeping my iMac and adding a TB RAID is a better choice for me. I'm hoping the new MacPro will come with different configurations in the future. At least I'll be able to move the TB RAID over to it then.
