Are you familiar with the Infinity Engine games that are the spiritual predecessors to this one? I have an extremely overpowered gaming rig but I can still load Planescape: Torment and become fully immersed not because of the mind-blowing ehhrrmahgawd graphics but because the writing, story, and atmosphere are so engrossing. I believe that this is what PoE is going for. They're not trying to blow you away with the graphics as much as immerse you in an entirely new universe through great story-telling and classic mechanics.
