From time to time I will test and see if the latest version of photoshop will install in Wine using the development branch. Now, expect it to fail a few times as you need to tinker but once you get it it's like you just conquered the world.

If you are using Linux you should embrace gimp but if your work is serious in any way make sure you got photoshop running under wine as Gimp equals probably to version 7 or maybe 9 or Cs but it's not cs6 not even close and whoever says otherwise is utterly incompetent with the tech behind the software.

Also most if not all your windows software will run under wine, game maker works, rpg maker works, photoshop cs6 works( I got it working ) but there is probably some software that won't work but there is more than likely an alternative.

here I am running cs6 in a virtual machine under my moms PC as I was kinda bored today..
