Help me choose a new PC

[GonzoStyle]

I know nothing when it comes to technical shit about computers so I need help. I do know that after 5 years its time for a new comp. Time to upgrade from my 63.0mb of ram and my windows 98 os.

Heres the comp I was eyeing:

Compaq SR1620NX Desktop

An AMD Sempron processor, Microsoft Windows XP Home, enhanced protection from viruses, and a one-year limited warranty are just a few features that make the SR1620 an excellent value. It's perfect for e-mail, word processing, games, music, and more.

AMD Sempron processor 3400+ 2.0GHz
160GB 7200RPM Ultra DMA hard drive
512MB DDR PC3200
DVD+RW/CD-RW combo drive
Windows XP Home

It's about 460 bucks after the rebate, I don't use my comp for gaming so I dont need anything special. Mainly I just surf the web, download torrents and play music. But I need something that doesn't have a panic attack when I download torrents and wanna open a webpage at the same time.

Also the guy at the store said that I could burn dvds I download but if I wanna copy actual dvds I have to get a seperate drive for that. He said a drive is about another 90 bucks or so.

So is this a good pc or is something better available for the money I am spending on this? I don't really wanna go over 550-600 with the extra dvd drive, naturally I just need the tower.
