So really, I'd advise getting a proper gaming computer. I just don't think you're going to get a good performance on a lot of games.Ģ017 mbp only runs an AMD Radeon Pro 450 which is much better.

It ran the hd too hard, and I noticed it would get pretty warm after awhile, because externals don't have fans like an internal gets.Įxternals really aren't MEANT to be used to run an os, which requires constantly read-writing when you use the computer.Īs well, most macbook pros actually DON'T have a video card capable of handling a lot of games.Ģ015 mbp runs an Intel Iris Graphics 6100, which rates just above a GTX 460m. I ran a mac completely off an external for awhile and didn't like it. At the same time, it's nice to have a computer that's completely dedicated to the os.

With Mac, you're paying for software, and I do love the OS. After all, inside, it's all the same hardware. I run a lot of games off my imac and it runs them well. That said, imo your BEST option is to get a PC for gaming. That could be a plus for running the OS and the game off the external. Usb3 will give you up to around 5gigbits/second, thunderbolt 2 will give you 20, thunderbolt 3 will give 40. Earlier mbps would have a Thunderbolt 2, which is still twice as fast as usb3, but not as fast as T3. Rather than trying to run from a usb3 hd, I'd advise getting a thunderbolt 3 enabled hd rather than usb3, but ONLY if your mbp is 2015 or later. So, I kinda like to think I know a little about this. I've also opened and replaced parts on both PC and Mac, so I'm familiar with what's inside. I also have experience with the 2015 MacBookPro because I bought one for my son.

I've used windows 7,8 and 10 through bootcamp on both iMacs. I've used Macs since 2006, and have used every version since 10.5.
