I am a KDE user and every Ubuntu release, I try the latest Unity or Gnome (back in the old days), release. Since 11.10 KDE outperformed unity on my system and testing it wasn't pleasant; scrolling was slow and the UI wan't snappy.
I do not have a high end system but it should be able to run any DE properly since it basically is capable of this on KDE.
CPU: Intel Atom x86 1.6 Ghz FSB 533mhz (motherboard overclocks it to 1.8 Ghz I think)
Memory: 2GB DDR2 FSB 800mhz
Graphics: Intel GMA 950 (945 express)
Hard drive: 5400rmp HDD
Has anyone used Ubuntu 12.10 on similar hardware and is it fast?
