Re: WoW performance.
When I played WoW several years ago I would run it under wine and get ~30fps (with the lowest settings possible). If you go to wowwiki, they have a page for setting it up under wine that gives you little tweaks you can do.
Also, Blizzard *may* be releasing WoW (or another one of their games) this year for Linux, so you could just not pay them until the Linux version is out...
Add me as a friend. Kill zombies/aliens/nazis with me. ON LINUX.
