Let me be more specific: you might mean Compiz... yes, it's one of the best windows managers out there. However, the GPU support is very poor on Linux. I recently had to deal with an AMD E-350 based box and there's practically no support for its hyped IGP. I had to do quite a few tweaks to get Compiz running more or less smoothly. So that also kills another myth about how AMD CPUs are magically shining under LinuxLinux has done this for years.
