Hi guys! I'm planning on buying a 13" retina very soon, since my 4 year old macbook pro 13" just isn't good enough anymore. But I'm in a dilemma...macbooks are pretty cheap right now, with back to school discounts etc., but I know there are new models coming out real soon with haswell processors (but the price will go up). As an architecture student, I use my computer for 3D and CAD modeling, photo editing, heavy multitasking etc. I don't really play any games. Would it make sense to wait for the new mb generation, or are the gains in performance low enough for me to just go with the "old" model. Thanks!
