  1. Hi everyone. I am looking for some direction/advice on setting up an eGPU for my rMBP. I am more of a software and cloud networking guy then a hardware/graphics guy - so I am out of my area of expertise here. Any assistance is greatly appreciated. NOTE: I have a multiple display/monitor addiction. The more monitors the better - and that is the main reason I am here. My current setup: Mid 2012 rMBP 2.3 GHz Core i7 8GB Ram NVIDIA GeForce GT 650M 1024 MB integrated graphics Two (2) 1080p 24 inch external monitors (one connected via thunderbolt port, and the other connected via HDMI) One (1) 1080p 21 in external monitor (connected via the other thunderbolt port). So yes, I am running three (3) external monitors off of my mid 2012 rMBP. And, it actually runs fairly well. Include the rMBP display, and I am running a four (4) monitor setup. I can usually have youtube playing on one monitor and browsers on the other, while still maintaining decent performance. I am actually really surprised at how well it works for a 4+ year old computer. However, there are some apps that I run which require me to unplug one or two of the monitors, and the rMBP is almost always running hot. And obviously, I can forget about doing any kind of high-end gaming (which I rarely ever do at all). Where I am going: My company is giving me a spec'ed out mid 2015 rMBP (which I should have in a few days). Mid 2015 rMBP 2.8 GHz Core i7 16GB Ram AMD Radeon R9 M370X 2048 MB (dedicated GPU) I am very excited to get a nice spec bump over my 2012 rMBP, especially going from 8GB to 16 GB ram. And I am sure performance will be that much better with my three (3) external monitors attached. What I want: More monitors! 4k monitors! Here is the setup I would like: My new mid 2015 rMBP docked (probably using something like the Henge vertical dock station). Run five (5) external monitors - one vertical and 4 horizontal. Monitor (1): Supplement the rMBP display (since it will be stowed in the dock) with a 24 inch 4k monitor. Monitor (2): Another 24 inch 24 monitor Monitors (3), (4), and (5) - these no NOT have to be 4k. Will probably just use the three (3) external monitors I already have (mentioned above). Priorities: Gaming is NOT my priority. If I can play GTA 5 in ultra mode - great! But I would consider that an extra benefit. I rarely play new games. I am more of a 16-bit, 2D platformer guy. I have done some VR development, and if I could run the Oculus Rift or Vive - then that would be really nice. My main priority is to power all these monitors while removing at much load as possible from the rMBP - so that I can run virtual machines/edit video/have 50 chrome tabs open - all while playing and HD youtube video (you get the idea). Here are my questions: (1) Will using an eGPU offload a lot of processing power so the rMBP can concentrate on running many apps at once? (2) If games are not a priority, are there graphics cards that may be cheaper which are designed for running more monitors vs. powering games? Or is it all one in the same? (3) I notice that many GPUs only have 2 or 3 video out ports. How can I go about connecting 5 monitors to the eGPU - if it is even possible? Or, would I still need to run one or two monitors directly off the rMBP? (4) Am I missing any details/information/questions that will be important? What am I missing or not thinking of? Thank you in advance for all and any advice.
