Anyone started using Windows Resolve fulltime?

I'm sitting on the fence here. If Apple won't make a workstation with more internal PCI slots, I see no point in upgrading to a new Mac Pro. I currently have a 2009 2 x Quad 2.26GHz - it does the jobs well.

Cubix expander with a couple of GTX 570s or 580s? Or should I go for a SuperMicro with a Quadro for GUI and a few 580s for processing?

The price of the SuperMicro+GPUs is tempting. But I have no other experience with Resolve for Windows except for the beta at my home PC with a single GTX560Ti.



Have anyone started using Resolve on Windows? Any problems? Any bumps in the road? Are you using the suggested mother board/Z800/SuperMicro as mentioned in the Config Guide?
