what are they? what does one have to look at? what are the different ways to evaluate a cpu/mobo so I can know what each will do for me and which one's I should get. i'm trying to spec out a new machine but I'm not sure what to get for it. one thing i know is i'm not a gamer. I use the machine purely for web/graphics programs like photoshop/illustrator/dreamweaver and for listening to music, watching pron and other vids. i just want it to be super fast when loading up programs and files and when working in photoshop. what would you guys recommend? thanks.
