Sorry as you can tell I am a newb to this. But I want to get started building my own systems. I am going to buy the e6600 when it price drops on July 21'st. I was wondering I am going to be building it for gaming. I was going to build it for wifey for photo's and crap but I decided to let her keep the Dell Dimension 8400 instead. Anyways. What is the difference between Mobo's? I hope that isn't too general of a question. I know there are differences with what type of slots it has. But what are the main differences? Is it ease of OC'ing? Sorry, one other question. what is the benefit of SLI video cards? Thanks in advance for any and all help.
