Unless you are made of $, or need this card for semi-professional and scientific work, its price will forever make it laughable as a
gaming card. This is Titan repeat all over again. With
how quickly GPUs advance and
the rate of their depreciation, for any rational person it will not be possible to reasonably justify a $3,000 gaming GPU, even if it somehow ended up even 10% faster than R9 295X2. Also, you could still buy 2x 295X2s for the same price negating any advantage Titan Z may have had!!
Some say that having a GPU with water cooling is a negative but to me that's a positive - lower temperatures and noise levels in a dual slot design. I'd rather prefer the Titan Z to be a water-cooled dual-slot card, than a triple slot air cooled card. The success of AIO in the CPU space is actually a testament that moving to water cooling for GPUs will either force air coolers to improve significantly (NH-D15) or result in PC gamers benefiting from cooler and quieter GPUs. +++ in my books.
Further delays of Titan Z only exacerbate this card's horrendous product positioning as a 5K gaming card. Next year we should be able to buy dual GM210s for $1,500, a setup which will probably pummel this card by 50-60% (even more in 4K). Lastly, lower power consumption on this level of card is irrelevant for high-end PC gamers. It's more of a marketing exercise for NV to showcase their ASIC binning abilities and the performance/watt of Kepler architecture. But with Maxwell's GTX880 less than 7 months away, who cares about Kepler's performance/watt anymore? NV should have never marketed this as a gaming card and then they could have priced it at $4,000-6,000 and none of us would care. At $3,000, and marketed as a gaming card, it shows a certain level of arrogance, reminiscent of the Titan's pricing, that may actually create some negative publicity for NV in the PC gaming space.
