I just built myself a major new box for my photo business:
Athlon 64 X2 6000!
4 GB RAM
dual Seagate 250 GB SATA 7200 drives
etc, etc.
Well, obviously, it also makes a great cruncher. So, I need someone else who runs an Athlon 64 X2 with Windoze XP 32 bit. That's so I get credit with that funny homogeneous redundancy thing they do. That's you, baby! You process mine and I'll process yours.

(OK, it's a wee bit more than I need for Photoshop, but hey... )
