I dont know much about computers and what makes a good computer. What do i look for when buying a computer? that is in terms of brand, processor, ram, disk space and yeah other stuff like that.
I found one here on sale, im not sure how good it is.
I want to be able to run many windows at once as if this computer was used to watch alot of multimedia and gaming. I plan to run itunes, youtube videos, MSN/Skype and all that at once along with alot of interent tabs.

Here is the sample product
