Will my PC be able to play this game ?

If you have wondered if the latest game will be playable on your laptop or a friend has asked you this question, head over to Can you run it ?
It will load a java applet and match your system specs to the minimum requirements for the selected game. The game database is kept up to date, so you should be able to find the latest and greatest.
Its detailed enough that, while my wife's laptop came up as a fail for Left 4 Dead it was due to the Intel mobility chipset not being recognised as valid (not ATI or Nvidia), but the specs showed it had the right shaders, ram and actually passed all the requirements.
