Newbie questions on Gaming and computer setup

Hey whatsup guys. I was wondering what i need to do to get a PC version of COD4 running on my IMac that i bought back in September 07. Right now I have 1gb of ram which i'm sure will need updrading to at least 2-4gb. Where do you guys go to buy ram that's cheap? Also, I'm assuming i'll need to upgrade my OS to OSX Leopard? other than that what would i need. Any help is much appreciated.

You need to use BootCamp and install Windows.

Boot camp is a feature of Leopard, it was just in beta for Tiger. So, you will need to upgrade to Leopard.
