Video Card Useage / (sever build)

Hello,

I am looking a build a low power (watt wise) sever. It will be designed to host a couple of websites, email client, a ftp site and a couple of vm's so i can bot a couple of games on it. I am also thinking about using Microsoft rdp or maybe vnc enterprise to control it.

I'm looking to put in a tri core amd processor that uses like 65watts, and like 8-12gb of memory (leaning @ 10gb)

I have no idea what type of Ethernet card i should put it. (need help)

The os might be Microsoft sever 2008 or just windows 7 professional (which one would you choose?)

Now my main issue is if I am checking the sever on my phone or another computer using VNC, Which devices video card will be doing the processing? Would it be the severs of my phone/computer?

 

Any one? My friend told me its the remote device
