Cant wait to upgrade my CPU later this month so that I'm sitting at something like 50FPS on the main, and 20FPS on the alts...

Till then I'm stuck at ~20FPS on the focused window, and 2 on the background windows.

Computer:
AMD Athlon 64 3800+ (2.39Ghz)
GeForce 7900 GS
2GB Ram

Monitor:
Dell 24' Widescreen
1920x1200
Main Resolution: 1280x600
Clone Resolution: 640x600

I have 6 wow folders. 1 for "normal" play, and 5 for Multiboxing.

This way I can setup diffrence hotkeys, macro, add-on's, and etc between each copy.

I use Keyclone for my keyboard broadcasting, and Maximizer to set my resolutions.

You can build a computer that can run circles around mine for about $500 now.
