Posted another PC in the OP. Should I up the processor and video card? C'mon guys hold my hand!

Alright thanks guys. The main reason I was looking at Dell is because they would build it for me, plus that free monitor is nice. The only experience I have with inside a computer is popping in a Gigabyte of ram about a year back. And when I did that I was so paranoid I was gonna mess something up.

Found another at AVADirect.com Gaming PC, Smart G31 Gaming System

I'll be able to buy more memory yeah? All the other desktops I was looking at had 6GB and 8GBs. Will 4GBs be enough? And the video card is the one that is included with the price. Should I just use that one or should I upgrade to another?

Bungie said spring 08 so yeah...they didn't give an exact date.

Is there a way to transfer music files from one computer to another? Or do I need some kind of special cable? I'm connected to a router, so both computers are on the same network.

Well I just bought the Crackdown DLC and I have 200 points left over. Any suggestions what I should buy with them?

EDIT: Remaining...

I read somewhere that if I create a new account on my XBox360 it will give me an Xbox LIVE Gold account free for a few months. Is that true?
