Seriously, if you really need to run a dedicated version of windows, then just buy a cheap HP with Windows 7. You can use your Mac Pro to login with VNC or Remote Desktop or something. No need to clutter up a Mac Pro with a copy of windows.
And if I want the computational resources of my Mac Pro? Why are you assuming someone who has bought a workstation, and wants to run windows, doesn't want to do workstation tasks in Windows?
I rather think the Mac Pro has enough headroom to run Windows in a fashion such that the 5-10% is not missed.
I tend to run resource-limited jobs - unless I'm being really sloppy with variable creation and I max out my RAM well before anything else, I'm running pretty close to 100% utilization in some cases. I'd miss 5-10%, since I don't bill by the hour.
because most users dont need that extra gain? whats your use case? if its legacy windows software, you dont need it. if youre doing windows development (me), you dont need it. gaming? MP isnt marketed as a gaming machine...
SAS. Some other scientific computing tools that are Windows-only.
agreed, but then he wouldnt get to say "bare metal".
here in enterprise land, we use VM servers for everything these days.
We don't. We have a mix of VM servers for public facing application hosting, and standard (since apparently saying "bare metal" is an invitation for derision in your world) servers for most compute jobs.
My Mac Pro has a bootcamp partition, and Parallels points at that. Best of both worlds, and I'd be miffed to have that go away. Windows 8.1 is tolerable (I've got it on my gaming machine, cheap license was cheap) but it adds nothing above Windows 7.
