The refurbished store is offering the first model in my title for an astounding $1299USD, which is a deal I almost can't resist. But the latter model is only $150 more, and the only differences are the processer, the GPU, RAM, and Supredrive speed. This may seem like a lot, but the processer difference is minimal, the GPU I don't know much about, I'm going to upgrade the RAM anyway, most likely, which leaves the the Superdrive speed. Any input on which model I should buy? I don't really NEED a laptop now, and I could possibly wait till June for Montevina, but is it worth it? Input much appreciated.
