Heard about this last year that you could play a high spec game on an old crappy pc hmmmm I thought that will never happen
Holy crap it has and it bloody well works.
I plugged in my old lappy
2GB ram 
2.1 dual core 
Nvidia 310M 
and here is what I got

Merto 2033


Alien vs Predator


NBK2011


what the hell
It takes about 20 seconds for a game to load

Try some demos and see for yourself and give me some feed back.
