Whynot

With multi-panel 4k support not being a major focus of game developers (or even 1080p at this point), major noticeable differences in game experiences seem to be minimal at this point -- with higher resolutions and multi-panel displays really shining in the workstation environment. Unfortunately, NVIDIA appears to have pulled a lot of work-station capabilities (such as floating-point precision) out after the Titan series preceding the Titan-X. Therefore, 980ti seems like a good choice for a gaming rig, while the Titan series is only moderately more efficient with gaming while losing all of the non-gaming thunder that originally made the Titan series a more appealing, one-size-fits-all solution.
