The Story ---
When I built my previous rig about 1.5 years ago, SLI 770 2GB cards w/ 3570K I had no intention of 4K gaming. Not a month later I bought a Samsung 4K 60Hz monitor, and then soon after that the Acer 4K model. I quickly realized that while I could play a couple games maxed at 4K, most games I could not without either terrible frame rate or running out of video ram. Recently that rig has started having some motherboard issues so I said **** it, we're building a new computer.
As a Software Engineer I spend a fair amount of time developing software and thus a big use of this computer will be software development, of which it is completely overkill for. However when I am not writing software or browsing the webs I am playing games. Unfortunately I can't stand not being able to play my games maxed with whatever hardware I have available which means maxed settings at a 4K resolution achieving at least 60fps.
I plan on getting an Ultra Wide 1440p monitor (probably the Acer Predator w/ G-Sync) once the price comes down a little. Once that happens I'll probably retire my 4K monitor as a secondary keeping the ultra wide as the main screen.
