Yes, that's my current spec friend(although I'm waiting for my new mobo and thanks to some friendly advice from some very helpful members of this forum I'm now looking for a dual core to fit). The game runs superb at 1280x800, all settings on highest, with AAx2. Frame rate varies between 30 and 40fps. I would recommend giving it a try. You do have to own Hl2, Ep1 and Ep2 and have them all installed with at least one save game each. Also they say to run the light version with 32bit Windows and the full version with 64 bit Windows but after initially running the light version I'm now running the full version on 32 bit Xp with no problems. See Fakefactorys site for further details.
