So WoW just crashed.

Just dinged 70 on my 5 shammys and was doing av, when wow crashed due to runtime error i think it was. Heh.
5 boxing on one computer with two screens. In shat i run around with 10-15 fps and slaves are always capped at 20 fps. When i run around in normal places like vanilla wow i have around 40 fps.

I have 1 desktop and 1 laptop. The laptop has vista (lawl) and has i dunno, 50-60 ish fps with 1 box.
What i'm wondering; is there a good way to setup the two computers so i can 5 box with everything going semi-smooth?
All i expect is for WoW not to crash in AV, and be able to see alliance. As it is now they arent rendered very fast.

Been serching around here but couldent find anything spesific for my case.

Thanks

you will need to publish specs of your machines before people can provide you with some pointers

2g ram. xp, duo core 2ghz e8400 nvidia gt7800.

laptop is 2g ram, vista 1,9 ghz. nvidia 7000m

Another thing: wow is running at 50% speed. not lagging just running at 50% speed.. 1,5sec cast time = 3 sec.. when i see timers in bg's and its say 15 sec left. after 30 sec it reaches 0. Which is reeeeeaaaly annoying when alliance attacks me at the isle.

*EDIT* Best way to explain is that when i get on a flightpath to a destination, and when i'm say 15-20 sec away from that place i jump from 15-20 sec away from the destination to the destination. For instance the daily with the air strikes; i need to use that item faaar far ahead of where i really am. If i use it where the circle is green it says "out of range". If i use it where its gray/red and where my character actually is, it sends out the air strike.
