I haven't used Bootcamp since I put XP on one of my long-gone macs years ago and so am way out of date on using it. I have a 5K iMac arriving tomorrow and would like to put Windows 10 on it but my main drive is a 512 GB SSD. My main reason for Bootcamp is gaming. I have 2 options here: A) Partition about 50 GB of the SSD to install Windows 10 and a few games and ~1 TB on external for more games. B) Partition ~1TB on external for Win 10 and games Will I notice any drastic graphics performance hits by going with option B vs. A? I'm aware that games won't load as fast from a spinner as a SSD. I'm mainly concerned about FPS*. *And yes, I'm aware that if FPS is really that big a concern I should have a dedicated gaming PC. I'm just trying to maximize it with the hardware I got alright!
