Ultrabook for moderate gaming?

Is there a 14-15" ultrabook that's strong enough to play games like ME3 or Skyrim at medium resolutions and med-high details at +30 fps?

In other words, are there 14-15" ultrabooks with dedicated graphics? 630m/7670 and above?

Thouchscreen is not a must, but it would be much appreciated for bed surfing.

EDIT: Today, It became clear to me that two type of devices would suit me..

1) Yoga

- if it was larger and had graphics

2) intel core tablet (w700) if it had thunderbolt and if there were external graphics.

tablet + ext graphics + monitor, mouse, keyboard, storage array would make for a perfect combo. but i guess we're not there yet.
