Am I the only one that thinks the water-cooled laptop is ridiculous, stupid, and defeats the purpose of a laptop? Also, if you're going to have an external radiator why not an external desktop GPU?
The difference in performance of the mobile 980m and the full 980 is about 25% more performance for the desktop chipset, so it's fine. It would be nice to have an external graphics dock for future GPUs that far outpace the internal one. I assume with the water cooled laptop, that the GPU is not on an MXM slot and so not upgradable.
It is a niche laptop but it'll overclock more than any other laptop (hopefully).
The water cooling dock is likely significantly less expensive than a external GPU dock + a GPU.
And if it cools the CPU too, very nice overclocks on it as well to bring new life to the laptop.
It'll perform great on the go, and be a total beast when docked (IF the AC adapter and safety guards don't bottleneck it). If the GPU is upgradable, I think it's fantastic but probably not upgradable.
Would be killer to have a dock for the dock to chill the water with a compressor or peltier.
