It depends.

What are your use cases? If it's just for a headless, common virtual
server setup, with remote access using rdp/vnc/whatever, then it
shouldn't matter.

Vt-d is important if you want to use pci or GPU passthru, but GPU
passthru is kinda hit-and-miss, with some hardware combination better
than others. Search the list archive for GPU passthru if you're
interested in this. If you're an average end-user, chances are you
won't be needing this.

vpro might be useful for remotely controlling the physical server, but
an IP-based KVM or server-grade motherboard with remote console
facilities can provide the same functionality.

As for others, just do some research. I'm not sure those capabilities
are even used by xenserver right now.
