hi everyone, i'm an engineering student and about to start my master thesis. my "old" 15" macbook pro is having logic board issues, and replacement at the apple store will cost me about 400. a friend of mine it interested in it, and would buy it from me even prior repairing (he would take care of that). that said, for a "small" price difference i could get the new 13" rmbp with 8gb ram with 12% off the full price. my current mac is an i5 2.4gh with dedicated nvidia 330m. the new one would have also an i5 2.4ghz with iris graphics. will i experience any speed improvement moving to haswell? let's not consider the ssd for now, i'm interested in raw performance to do some fem simulation (for which i will need a windows partition). should i rather fix my old 15" and add an ssd to it? i'm also concerned about screen estate, in my current macbook i have 1680x1050 resolution, how is windows dealing with the retina display? if i'm back to a "simulated" 1200x800 i'd rather kill myself! any comment and suggestion is well accepted!
