I'm seriously looking to buy a new computer within the next 6 months. I know for a fact that I'm not looking for the biggest and best system just something with lots of Ram, XP, and preferably a P4 processor or a comparable AMD chip. I plan on mainly using it for the internet and downloading MP3s back and forth from my MP3 player as well as some school work (reports etc.). Given these uses and my wants what should I be looking for? How much Ram and how much processor speed do I really need? so far I've started looking at the Dell 4550 as well as some local computer store's machines. I would really prefer to keep prices in the $750-$900 range. Thanks.
