Running 3 External Monitors off a Mid 2014 MacBook Pro I have a MacBook Pro retina 15 inch. It's a retina model with a i7 4980HQ 2.8Ghz quad core processor, a 2GB Nvidia GTX 750M graphics with 2GB VRAM and 16GB ram. 

I was wondering if I would be able to connect 3 monitors to it to use mostly for coding, but perhaps also some occasional gaming. 

would the best way to do it be through the two Thunderbolt ports using a 2 Thunderbolt-> DVI adapter and one monitor through the HDMI? 

Will they all work properly, will there be any difference in quality if I'm using 3 monitors of the exact same model.
If you Google Mid 2014 MacBook Pro and go to this link Apple says "Dual display and video mirroring: Simultaneously supports full native resolution on the built-in display and up to 2560 by 1600 pixels on up to two external displays, both at millions of colors."

I added the emphasis.
