Someone post some videos. As far as i have seen, the graphic cards are powerful enough to bring recent games in high settings and 1080p. and that isn't yet optimized for consoles. so... they may be weak. and they may be cheap. but the graphics will improve in a good amount of time.
must-have-list for platforms i don't own yet:
WiiU: Donkey Kong
XBone: Dead Rising 3, Ryse
