Started dual-boxing 2 warlocks yesterday, was getting 40-50 steady fps in azeroth, 800x600, everything on lowest and some things turned off for performance.

(using autohotkey atm)
computer details:
AMD Athlon 64 3000+ (socket 754)
Ati 9600 XT
768mb DDR (not 2)

my question is, could i still dual-box in outland with this computer? since ive heard stuff about it..
GFX settings (right click on desktop etc) are "balanced" if that matters, using 1 windowed and put to the smallest size possible, and the main is windowed maximized.

also tips for better fps (if that drops in outland or whatever.) appreciated, except "buy a new computer".
