Surface Pro 2-Spec wars

Microsoft has won my money with the surface pro 2 and I'm eagerly waiting to fork over the cash. Since it hasn't been released yet I've been doing a lot of thinking on which model to get. Just a question, is the 8gb ram max really necessary? I'll be using it to take notes in class, consume media, play a game or two(league) and just use it as my laptop. I really want this machine to work flawlessly which is why I'm ready to splurge and get the highest option, but again....... Is the 8gb ram really going to be worth the extra $$$?
