oh and uh... how do I take screen shots? thanks.
Screen shots are easy. Just hit "Print Screen" and then open up your paint program and select "Paste" and paste the image into that. Or alternately you can download a screen shot utility (best in my opinion). There are a number of them available. Just have a look through the file library. I use YAFScreen myself and FScreen (older version). There are several others and anyone you ask will have a favorite.
Some unsolicited advice. Go to a computer store and have them build you a PC. Those package deals like Dell and other companies usually include a few good features and a bunch of low end features. For example you may get a huge hard drive and great processor and then they throw in an onboard graphics card.
For best performance you want all components separate. Start with a good processor and MB then add the components onto that (memory, graphics card, sound card, drives etc. This way you can upgrade easily, if something breaks down replacement is cheaper and you get exactly what you need without features you will never use or features that are less than you need.
There are many computer stores who will build a machine to your specifications and they'll also let you tell them what you want and then suggest how to set up your system.
Personally that's what I suggest as the best way to go.
