Publishing Web application recommendation

Hi!

We have a hyper-v HP Server with Nvidia GPU which we need to use for publishing a web application on a VM. As per our knowledge it is not possible to assign GPU to VMs having Server OS. In this case we have two options, either we create separate windows 8.1 Enterprise VMs for every user who needs to use that application or we install the GPU on a separate physical server, install windows server OS and use Remote Desktop Services to let users use that application.

Which option is better and is there any other solution. The application is highly graphical and needs a good VGA. That's why we decided to let users use it directly on the server.

Thanks.
