I built my own desktop with a gtx780. I use it for gaming, but i am almost never home, and i dont like having a fixed position. I am getting a 2013 13 inch macbook air, and i was wondering if it would run games like league of legends, starcaft 2, garrys mod, and minecraft. Also, i dont need or want a retina display. So would that macbook with intel i5 and 4 gigs of ram run games decently?
All of the games you listed support Mac OS X. You might want to check the system requirements for each game though StarCraft 2 LoL Garry's Mod Minecraft Some games might require flash or java. Also try not to run other programs while playing these games due to your low ram size.
