It works very well. Gaming needs a little help, as do graphics, but if you're willing to work with nVidia cards, you get spectacular graphics performance. SLI is catching up to the Windows side quickly.
Also, Linux will run on just about anything. x86, ia_64, AMD64, PPC, ARM, DEC, SPARC/UltraSPARC, you name it.
I use it for everything - graphics (GIMP or Photoshop-on-Crossover), gaming (not all games work, but most work well enough), audio (I run SHOUTcast broadcasts from my machine, as well as recording and mastering), web/software devel, and just about anything else I can come up with.
