Also I can tell you gimp will do just fine!
Native linux games are also so much faster with lower GPU temperature. Also steam is making so much progress on that.
Anyway you should understand that using Linux is not about ease of use or speed. It's about your freedom and your right to see through something you buy or use.

There will be so many forks trying to continue a Kernel based on linux and i think a few will succeeded! We may use arch kernel or debian kernel in the future.
