Honestly, this seems somewhat pointless. If your compute workload is intense, then you probably want to do things on a remote server with 2-4 GPUs and then you just want a small workstation card for visualization (heck you can probably just use an IGP).

I don't think it's a useful case. Besides, there are no workstation cards based on the GK104, and there won't be.

The workstation cards and Tesla's use the same GPU and it will be different than any consumer graphics part.
