As a hardware enthusiast, it's impossible to not fall in love with the GeForce GTX Titan X. NVIDIA has combined specification that drop your jaw: 3072 CUDA cores, 12GB of memory and 6.14 TFLOPS of peak theoretical compute (before overclocking). The look and style of the Titan X is still at the top of its class, despite the fact that I think it might be time for a refresh. The GM200 GPU is incredibly impressive in the performance department offering gains of 35% over the GTX 980 and 45% over the R9 290X. Only the Radeon R9 295X2 can beat it but it requires a pair of GPUs to do so.
NVIDIA continues to bundle high quality hardware with extra features and programs that are getting gamers' attention. You have full feature-level DX12 support, HDMI 2.0, G-Sync variable refresh monitors, GeForce Experience software with streaming/capture capability, frequently updated drivers with major game releases, GameWorks game implementations and more. Yes, you can debate the value and importance of one of those (and other) features and technologies but it is the combination that adds up to a package that clearly appeals to PC gamers. The market share changes through 2014 prove that's the case.
Obviously the one caveat to this is that price tag - $999 is a lot to spend on a GPU that offers "only" 35% better gaming performance than the $550 GTX 980. But, much like the Intel Extreme Edition processors that continue to be released, refreshed and sold, the market proves that these parts sell enough to warrant the cost.
