FPS Issues please help..

Hey im very new to community and have to say multi boxing is the most fun ive had in WoW in a long time. Anyway im trying to 3 box shamans my system specs are as follows

Intel celeron 3.33GHz

2 gig of memory

GeForce 8600 GT 512 MB

Now i know this isnt the best pc in the world hey it may be even close to the bottom but its what i got. Right now i run 3 shamans but my fps on each is anywhere from 7-15 tops. I was wondering if their was anything at all i could do with this system that would make it better without having to buy a whole new PC. Looking for cheapest way out basicaly. ANy help would be appreciated. thanks in advance

I'd say its a combination of 2GB RAM and the Celeron.

Buy a decent dual or quad core processor and some more RAM. (first make sure your motherboard is socket 775 and can take dual/quad cores.

Yeah, that Celeron is gonna kill you. Im running an older Athlon FX-57 at about 2.9GHz (man, that thing used to be awesome... ;( ) and I can get 3 screens running without too much difficulty. Im not sure I'd want to go inside a city though. Adding anther 2g of RAM will certainly help, but I dont know that it will be enough of a difference.

Your best and cheapest bet would be to replace mobo/CPU + RAM.

Good luck!
