When it arrives I will wipe Ubuntu and install Linux Mint KDE 12. It will be sweet. I know this because it is meant to replace my desktop (Athlon64x2 2GHz with ATI HD 4350 graphics), which is getting a bit long in the tooth now, and yet it runs KDE4 very nicely indeed with the open source AMD/ATI graphics drivers. Extremely snappy and responsive.
On Windows. This is a Linux forum and we're talking about the open source driver. The open source AMD driver is slow.
By your own argument there is no room for improvement in a machine with Intel graphics, the underlying hardware constrains it.
I don't see how this is important. Not a single person where I installed Linux on his/her machine even cared about the license of the driver. The only thing they care is that it works.
You must lead a very sheltered life.
