sorry for the mislead answer. I bought a few zotac recently and all
where ion based. We are using in house debian-live for booting x2go
terminals (http://live.debian.net/), and I had issues with outdated
nvidia driver in debian and all the rendering was done on plain vesa
driver, which needed a whole lot of CPU.

I'm currently running on a x2goclient running on a zotac (Intel Atom
D510, nvidia GT218 ION), and doing standard work (no intensive graphic)
takes between 5-10% cpu on the client side.
