I don't know about anyone else, but I look at this and it just makes me more anxious for the future. Not only does this card seem somewhere around 20% (10% overclocked) from where most using it would really like it to be, it sets a more clear picture of what to expect.
Games that are around 50fps 4k (like Tomb Raider or Shadow of Mordor) seem prime candidates for 14nm performance parts (ala a gm204 replacement with closer to GM200 setup or Fiji shrink)....but bumped up to having the ability (overclocked) to hit 60fps. Not only does that sound appealing (especially if nvidia switches to a more compute-heavy arch, similar to AMD for Pascal), there's probably also at least a chance those could be 225w (eventually, if not off the bat).
Likewise, games that are closer to what require crossfire/sli (ala around 37.5fps if you figure 1.6x scaling, like BF4) seem prime for what nvidia could pull off with a big chip within a year or so.
While I totally agree this (and likewise the 375w/WCE Fiji, for both similar and different reasons) are certainly enticing compared to what has been available at a similar price for a new build or long-term upgrader that has an older part...I just simply don't find it that compelling considering how close we are to options that will meet the demands that this (and perhaps Fiji) come painfully close to achieving, but can't really pull off (performance/buffer games do and will truly demand at 4k).
