wonder what the specs would be to get it running that good.....2 8800GTX's in SLI maybe? XD
EDIT: just seen this on the wiki page, "Fallout 3 is in production by Bethesda Softworks, who have announced that the game will use the Gamebryo engine from their previous work, The Elder Scrolls IV: Oblivion." so yea....specs will be rediculously high
