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?
Covered here:-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.
