I am planning to buy a beast for gaming and I kinda like the macbook pro (2.0GHz quad-core Intel Core i7 processor (Turbo Boost up to 3.2GHz) with 6MB shared L3 cache, 8GB of 1600MHz DDR3L onboard memory, 256GB flash storage, Intel Iris Pro Graphics). As windows can be installed on mac, will I be able to play all those games (especially Mass effect 3 , Battlefield 4, Pay day 2 , assassin's creed) that can be played on the alien ware and other holy laptops of gaming. If yes, is Intel Iris Pro Graphics enough or Intel Iris Pro Graphics NVIDIA GeForce GT 750M with 2GB of GDDR5 memory and automatic graphics is a mandatory? I just want my gaming beast to look like an angel(mac). I am really in need of a mac and a gaming beast because I make iOS apps and I am fond of games. Please help me. Thanks a million in advance.
