I like limewire. It's free. It seems to take over your whole computer though? Basically leaving you with limewire running perfectly and all other progs running very slow?
I recently got a new comp with 1 gig of ram but haven't tried it on it yet.
My old comp had only 128 megs of ram. Someone else told me that they had 512mb of ram and they still had this problem. I will try it out in the next few days on my new system and let you know.
Still, you can set up your downloads when going to bed and the next morning when you get up... voila!
