Switch off all sound on your alt characters
This should help a ton. My computer is quite similar (AMD X2 4k, 2gig RAM, 8800GT, WinXP) and I have no problem running 5 instances with the video turned down and the sound off outside of major cities. I run Keyclone Maximizer with main screen at 40ish FPS and the alts turned down to 10FPS. The performance difference between having the sound on and off is profound.
