The Wii U uses Radeon 4770 and DirectX? 10.1. with Open GL 3.0 This is a slight vatairion change in DX9? and is not much different from PS3 s RSX build. Wii U's main CPU the IBM Waston is also Power 7 based, not much different from PS3 s 4 CELL which is Power 5 based.Also, Ricardo is incorrect. Gamestop UK and MANY sources are stating Wii U will cost $399. In fact, pre-orders are 200 pounds The $300 claim is from Nintendo fan sites based on hearsay from a GameTrailers? editor. In the more credible sources, it states $400.The controller is the reason why the system will be steep as well as Nintendo Land coming packaged with the SKU. http://kdrzwmdwee.com [url=http://qmmpis.com]qmmpis[/url] [link=http://htkxkozck.com]htkxkozck[/link]
