I'm getting 25% off on a new Macbook Pro so I finally decided to take the jump. I think I have most of the specs ironed out except I'm still on the fence about the RAM. It comes standard with 4gb, and I'm debating if that will be enough? I will mainly be using the laptop for recreational use, when I travel home for holidays, sit on the couch, etc. So websurfing, and games like SC2 and WoW at friend's houses. Would 4gb be enough? The 8gb upgrade is quite pricey but since this is a once in a while type of purchase for me I want to make sure I do it right the first itme.
