Thanks for the advice! (It was given a few pages back).
Glad to hear that the Iris Pro graphics will give me a performance bump on what I already have. I'm wary of integrated graphics. I don'r know much about any of it, but I've always assumed they are not as good as a separate GPU. I must admit, if they have a separate gpu option when they finally come out, I'd probably go for that.
This is quickly changing. Intel is really stepping up their integrated graphics game.
