The device we had was powered by an Intel Core i7-3517U and is good enough to do anything you want, even do different stuff on the two screens. But we were not able to do that as the touch functions on the lid screen seemed to shut when you have something else running on the inner screen. We believe this is due to a software bug in the device. Then it seems Asus avoided having touchscreens on both sides due to power and processing issues. The Taichi is a very good, though pricey, Ultrabook and ticks most of the boxes in this regard. You will not have any issue as far processing power is concerned.
