I would wait for 700 series..Just me tho
The waiting game is not a game I wanna play.
You don't know when the 700 series will launch, it took over an year that the 600 series got released after the 500 series. The 700 series, doesn't feature a new architecture, so just a new kepler 770 with higher specs, nothing major. Like going from sandybridge to ivybridge I believe.
Limited to a laptop just for one night makes me see how much I need a decent gaming desktop.
