you won't be able to run that on eaither machine without at least 1.5-2 gigs of ram, 128 mb vid card is good.. and you need some raptor 10k rpm drives.. maybe even reg wd's sata raided or something for faster access when comp is that laggy.. and for sure better cpu's or double.. 2.. is ok but you will need ht technology or dual cpu's to get the multi tasking effect.. otherwise you will have so bad of comp side lag that you won't even want to play like that... go for it.. i will see what i can do, but no promises.. and even if i or someone finds somthing, gl with running it on almost any reg comp.
edit: also what speed is bus is your ram? that also make s huge difference.. is it dual channel? mobo? thats very important.. who knows most people have mobos that don't support anything more the pc2600 and higher than 250 mHz and also might not even support high amounts..
all those factor if you will even be able to handle it... i wouldn't like to hear about someone overheating their comp because they wanted to play 2 things at once

the mostbeating on your proccessors i would say..
some hl mod (ie cs

) and l2 at the same time... then while you are waiting to fill hp. you own some fools.. good times.. ill look on getting that for ya, but i wouldn't suggest running on there unless you are positive it will run it
