if a 2 year old machine is slowing up with internet downloads, the problem is probably spyware, unless your on dialup.   the quality of the machine realy doesnt effect how fast it downloads stuff.  however, 2 gigs of ram and a 3200 isnt bad. i usulay work with less than 1 gig of ram (500 mb used by windows. )  and i consider my computer realy fast.  if you want your computer to run alot faster, just reinstall windows and get an external hard drive to back everything up that you absolutly need.    otherwise, download spywareblaster and spybot sd
