So I'm looking for a new MacBook. I don't know whether I should go with Iris Pro or 750m. At refurb the Iris Pro at $1699 and 256gb SSD and 8gb ram. Then the 750m is at $2199 and double the Iris Pro's ram and SSD at 512 gb SSD and 16gb ram. I'm most going to use iWork, iLife, Photoshop, and a game here and there. Games are stuff like Civilization V, ESO, Minecraft, XCOM, Batman, TF2, Deus Ex and Borderlands 2. I've seen some benchmarks and I the Iris Pro about 5-10 fps behind but at higher resolutions the 750m is about 50% faster. So will the Iris Pro do or is the $200 upgrade worth it.
