The only one of these with Maxwell in its 860M is the NP7358, if that matters to you as it does to me.
My source: http://www.xoticpc.com/sager-np7358-clevo-w350ss-p-6991.htmlI also emailed a(n?) XoticPC rep who confirmed the 8000 series uses Kepler and suggested the NP7358 as the Maxwell alternative.
