Error starting RemoteFX VM with unsupported GPU

A bit off-topic for most of the posts on this blog...I didn't see this posted anywhere else in this context so I thought I'd share.  I'm working on a RemoteFX prototype for a customer and have a HP Z600 Workstation with a Nvidia Quadro NVS 450 video adapter that I'm using as the server running Windows Server 2008 R2 SP1 with Hyper-V and RemoteFX.  When trying to start the virtual machine Hyper-V Manager returns the following error.

An error occurred while attempting to start the selected virtual machine(s).
'rfx01' failed to start.
Microsoft Synthetic 3D Display Controller (Instance ID {GUID}): Failed to Power on with Error 'Insufficient system resources exist to complete the requested service.' (0x800705AA)

I examined the Applications and Services Logs\Microsoft\Windows\RemoteDesktopServices-RemoteFX-SessionManager\Admin log and found the following:

Event ID: 14
Level: Error
Description: The GPU named NVIDIA Quadro NVS 450 does not meet the minimum requirements for RemoteFX.  This GPU will not be used for Remote FX.  GPU: NVIDIA Quadro NVS 450.

Event ID: 3
Level: Critical
Description: The GPU or system resources are insufficient for this server to run as a RemoteFX host.  Verify this server's hardware against the requirements.  Status Code: 10.

While the error when starting the VM is a bit cryptic the others are fairly self-explanatory.

Nvidia has a blog post that lists their current GPUs that support RemoteFX; the Quadro NVS 450 did not make the cut.
