Do you want to run modern PC games on your tablet with multi-touch?
If yes, then you should strongly consider the Razer Edge Pro. It beats the Surface Pro hands-down in specs. As far as battery life though, not so much. However, more performance typically means more battery drain.
A faster processor than the Surface Pro comes standard in the Razer Edge Pro model, a Core i7 1.9GHz, 3.0GHz in turbo mode. (A huge leap past the Core i5 1.7GHz processor that resides in the Surface Pro.)
Also, much more memory. With 8GB of memory, it’s twice the mere 4GB that the Surface Pro offers. I wouldn’t take anything less than 8GB of memory in any laptop or desktop computer nowadays.
One of the Razer Edge Pro’s strongest features is its graphics processor. It wields a 2GB NVIDIA GeForce GT 640M LE which means a much better gaming experience than the puny Intel HD4000 with shared video memory.
On the go, the unit runs at 1366x768 but makes up for the lower resolution once connected to the dock, mentioned below, that outputs 1920x1080 resolution via HDMI port.
Couple the Razer Edge Pro with a mobile hotspot and you’ve got an instant mobile Steam gaming machine!
The two models of the Razer Edge Pro vary only in hard drive space. The 128GB SSD model runs $1,300. While the 256GB SSD model runs $1,450.

Also, remember both the Razer Edge Pro and the Surface Pro tablets ship with Windows 8 Pro, which means full-fledged Windows.
Other things to note:
The docking station ($99) for the Razer Edge Pro adds 3 USB 2.0 ports, Full 1080p HDMI out, and another place to connect your headset for online gaming. (I personally love my Astro Gaming headset.)
