Haven't read the whole thread but I'd like to comment on the whole "SoW will be Nvidia optimized etc." subject. No game developer in their right mind will make a game that runs better on one brand of VGA cards than another. It doesn't make financial sense, if you wan't to reach out to as many customers as possible you have to make the game work equally good on all different brands. Maybe 10 years ago it was different when Nvidia all but owned the VGA market but these day when it's so evenly spread you have to satisfy ALL customers. Many games have an ATi or Nvidia stamp but they work just as well on both respectives in most cases, it's mostly just a marketing ploy. This is just my own humble opinion though
