UBUNTU or XUBUNTU?

[eurgbp2011]

I want to install 6 GPUs 5x6970 and 1x5970.
Installed them all successfully on but Win7 x64 cannot work with so many GPUs only 4 GPUs accessible
Which one to install UBUNTU or XUBUNTU?
What's the difference?
Probably none? just cosmetics?

You'll be able to mine with both. The main difference is that xubuntu is lighter. So you want to setup a rig running on USB stick with no drive, you may prefer xubuntu for example
