Alright, so circumstances have arisen to force me to buy a new computer. But I find that I can't tell the difference between what's good, and what Dell says is good. So I'm asking for some help. To start with, here's my old computer.

hp Pavilion 325c

2.0GHz
512mb DDR SDRAM
60GB Hard Drive
ATI Radeon 9250

I don't care what operating system is on the new computer when I get it, I am under the impression that if Vista sucks as much as it's supposed to I can just install XP or Linux. I almost exclusively use my computer for iTunes, Internet Browsing (on Firefox of course), and MSN. I save the gaming for my 360. I'm trying to keep the price on the new computer low. The lower the better in fact. Feel free to ask questions.

Any advice would be appreciated.
