Windows has been giving my mom's laptop plenty of trouble. We are both fed up with BSODS and crashes. Please don't comment that I need to get the PC checked on by Geeksquad first.

I want to know what I should dual boot on her hardware, Ubuntu 12.04 or Xbuntu 12.04.

She is running Wndows 7 64 bit, i3 tm 4 Cpus @ 2.13, with 4 GB of ram. THe graphics card is an intel chip.
