So Im about to buy a new macbook and I have about 1200ish to spend not counting tax/shipping. Is the 13inch macbook air with 8gb of ram,dual core i7 and 128 ssd be equal to the retina 8 gb of ram dual i5 and 128 ssd. I do play some light games and plan to use a micro sd card for extra storage. Would the higher res screen on the retina lower performance in games or is that compensated by the iris pro? As for games I would only be playing league of legends.
