Powerful Windows 8 Laptop/Ultrabook for Gaming and Video Editing

Hi!

I am currently looking for a powerful Laptop/Ultrabook with Windows 8, that has a discrete graphics card for gaming and video editing, and an 256 GB SSD.

It would be great if it were a device with a touchscreen, or at least optimized for Windows 8. So probably an Ultrabook.

Is there something like that on the market?

Thanks,

Michael
