We were looking at this card:

It's just for a couple of users that need GPU, the rest we can arrange with terminal server without GPU.

AMD's Citrix and VMWare support uses a mode called GPU Passthrough. In both cases, the software allows a virtual machine to directly access a GPU. In this use-case, GPUs and users are mapped in a 1:1 model, with one card dedicated to each client. It's also possible for Xenserver to create virtualized GPUs, with up to four users per card. The implication from AMD's presentation is that Citrix is a bit farther along than VMWare as far as supporting various GPU configurations, and that Remote FX is the most mature solution overall.
