If it is that larger monitors require more GPU processing power, as opposed to "extended" displays, I'd love to know how you've come to that conclusion.
Normally, it's a pretty simple system of vertical and horizontal resolution of each display, times your frame rate. As examples:
(1920x1080)x60: 124,416,000 pixels a second.
(1920x1080)+(1920x1080)+(1920x1080)@60: 373,248,000 pixels a second.
The monitors could be twenty-four inches, or forty-two inches as far as the graphics card cares, from my understanding. It is all about how many pixels you're computing. A twenty-seven inch display may have 1080p which should create the same GPU load (assuming the refresh rate is the same). If it was 1440p, though, and 60hz, the load would jump to 221,184,000 pixels a second.
Yes, more monitors do require more GPU processing power, but the resolution will use the same amount of Vram, sort of. Yes you will use up the Vram on a 2GB GPU on mulitple monitors... if your using one GPU. 3GB, not likely, but the way I see it is that the raw gpu power is greater on the triple displays then the 1440p+ display, but the 1440p will use the same Vram. I was basically trying to say that a single 780 with 3GB of ram will work 100% perfectly. It probably won't run all his games at max, but granted, turn down the AA you can play at higher setting and use less Vram.

The GPU produces the exact same amount of heat, it simply gets dispersed faster into the room/case or wherever your exhaust is. The reason you see lower temps in your monitoring software is because the heat does not linger as long in and around the GPU are where the temp sensor is.
Heat stacks. Basically how I understood my science class is that if something can produce heat, and it is enclosed in a small space, the heat will essentially multiply and fuel itself, generating more heat, that is, if the thing that is producing heat is still generating it. Basically it causes the heat source, in this case a heatsink, to get hotter due to the hot air enclosed in the space heating up the heatsink further. So yes, technically the GPU will produce the same amount of heat, but the total heat produced is less if it is properly cooled. SCIENCE!
