A little more info on this: the i5 prototype I have, running at 7W (which helps significantly) was able to run LoL, which I tested for 5 minutes, at steady 60-100FPS with "normal settings" - default. So NOT all settings high. Ofc if you plug an eGPU rig to the side of the V, you can expect much better graphical performance.
@iKirin informed me yesterday that he was able to cool of the i5 @11W steadily. So let's say you'd be looking at overclocking possibilities at around 9-10W steadily, which is more than double of the standard TDP. Depending on the game title, you should be OK.
@dartarian1 tagged you as well, since you were talking about gaming
