    As you probably know, the non-retina 27" iMac can be specced up to a GTX780M. How much faster is the new R9 M295X compared to the NVIDIA chip?

    I'll let you know monday if someone doesn't before. Moving from a 2013 full specced unit to a 2014 full specced retina.

    I'd really wait for drivers and benchmarks to be updated before making any conclusions.

    That'd be awesome thanks! Seems like some other benchmarks place the 780M between the M290X and M295X. I'd like to see what you find though.

    These benchmarks should also include overclocking, which is a huge factor for the 680MX performance. Ie. what is the highest practical overclock that is 100% stable, and that doesn't increase the temperature any significant amount? Again, the 680MX still compares favourably to later mobile GPUs, because of its large overclocking headroom (+250/+350 being 100% stable with CPU turbo boost off, and using a higher static fan speed to avoid high temperature spikes).
    Also, does the image become blurry at regular 1440p resolution? Playing modern, demanding games in resolutions higher than 1440p is not a real option.
