The setup I've worked to build for ages, finally done. Both honorarily and legitimately named "extremist" per custom, and on merit. [ UPDATE: Swapped out one 24" HD for a 27" 4K ]
Not a gamer at present. Purely working with Celluloid+Ruby, maintaining F/OSS libraries, developing innovative and disruptive technologies. Kinda hard to beat the crap out of massively concurrent actor-based/evented multi-core code without a radical development environment. I deploy to the cloud and it's reasonably comparable performance, compared to needing to always develop directly on a clustered virtualized infrastructure. Everything about this setup is geared toward tuning highly sensitive actor meshes.
In one photo you see the top screen appears to look into another room. It's showing the entry security camera at 25% opacity. The background shows through and other windows go nicely over over it with me still able to see who comes and goes at the lab. Nice touch, thanks to Cinnamon's dimmer option depending on how I adjust each window's opacity by mousewheel, with the cursor hovering over the title bar.
Started with a three-head GeForce GTX 750 with a GT 730 added for the fourth display ( since the on-board graphics card is Intel, and nVidia is notoriously incapable of convenient and high-performance configurations across GPU developer ). Even with two nVidia cards, Linux/X11 with >3 displays was a nightmare no matter what nVidia driver version. Never felt just right. Always either slow or badly placed positioning, or both. Xinerama and RANDR always fought for supremacy at my expense.
Now it all "just works" ... after I replaced both with once GTX 960 Overclocked. It's perfectly configured without anything other than arrangement placements, tuned to the pixel. With that done, I'll be moving up to 4k displays in steps... starting with replacing the primary/central display, then those around it. ( UPDATE: I've added one 4k display to replace the primary screen. )
Pricing listed without the actual 8% tax involved. Shipping and rebates not included either.
Funny side-show in this build that turned out awesome without replacing the part involved ... the speakers are 5.1; but the Intel HD Audio ( Realtek ) interface on the motherboard and its connections only seemed to be 2.0 ... or are they? Thanks to hda-jack-retask my rear-pink Mic channel port believes it is a rear-orange Center LTE channel port, and my real blue Line-In port believes it is a rear-black Back channel port. That, and explicitly making my pulse configuration 6 channels versus 2, means I get true surround sound from the embedded audio card. Room filling sound at last!
