Thanks all for your feedback.

Seems however that i got an even cheaper solution: my GF's computer is more recent and can handle 3 wow nicely (maybe more, need to test - bloody tuesday maintenance!)

it's performance mark is double that of my own machine, which should be able to handle 2 wows ok. (3 wows crash only in Northrend)

so all in all, 3 wows on one machine, and 2 wows on the second
Now i need to find a cheap way to pass the keys from one to the other, .. either a second Keyclone licence, or some other way. i don't think i can afford ISBoxer subscription though. I'm stretching as it is..



Planned costs
- cross machine MB tool - $???
- upgrading 2 accounts from BC to WOTLk - 2x $40
- upgrading 2 accounts from vanilla to WOTLK - 2x ($30 + $40)
- moving 4 toons from main account to slaves accounts - 4x $25
Total = $320+

i might be able to use the scroll of resurection on some, so that might save me a couple months play here and there.
any thing else to think of?
