If you want to play high-end games on tablets, check out this video running Skyrim on the Asus Transformer Prime tablet.
Because the tablet would be too weak to run games like Skyrim you need a PC and can then stream the game to the tablet. This works unexpectedly very well and is not lagging.
Apparently the tablet is connected to the PC and you can stream it using the remote desktop app Splashtop THD. Splashtop develops remote desktop software for high performance programs. For more information you can visit their site at http://www.splashtop.com/
On their website you will also find a remote desktop for HP’s TouchPad, Splashtop Pro for businesses and a Splashtop Presenter for school/work presentations. Considering how popular tablets are now, this technology will be a lot more commonly used for education.
