I just bought the game through Good Old Games and while I meet the minimum specs (except the gfx card, maybe, I'm not sure how comparable they are) I can't get the game to progress past the "verifying 'Pillars of Eternity'" step. The game will try to launch, it'll be bouncing in my dock like any other application does when it starts up, but then gives up and says "This application is not responding" when I try to right click it.
These are my system specs, in case that might help.
Processor: 2.53 GHz Intel Core Duo
Memory: 4GB 1067 MHz DDR3
Graphics: NVidia 9400M (256 MB)
