Like the title says, I'm having a little problem deciding between weather to get the lower end 20in or the higher end. The only real reason why I would be getting the higher end 20 inch is so that it can play WoW well ( yes, I am pathetic), and I am concerned that the lower end 20 inch can't. I have considered that adding more RAM to the lower end might make it run faster. But I don't want to buy something, then have it not meet my needs, then have to get the higher model. I know all fo you will say get the higher end, it is worth it in the long run, but I can't convince my dad (He is paying part of it) to buy it. Any help?
