Best Windows 8 Laptop

I am looking for a thin and light laptop with around a 13-14 inch TOUCHSCREEN that allows me to play simple games like CIV 5 and SimCity and some light Photoshop/AutoCad with some nice graphics and good battery life (comparable to MBP). So far I'm looking at the Lenovo Ideapad Yoga (if Intel 4000 are good enough), the Samsung Series 7 Ultra, the Acer Aspire S7, or the X1 Carbon Touch. I am thinking of waiting to see the Haswell options (most of these will get updated I suspect).

Any recommendations?
