Fortunately, it's reported and therefore not heresay (at least from the player base). I have no idea of the credibility of the site, but you can judge for yourself.
The Windows version will utilise DirectX 9 and have support for Windows 7, 64 bit operating systems and multi-core processors. Soon after the game's release there will be an update to allow the game to utilise DirectX 11 features, which will require a new client download provided by Square Enix. The game will have support for multiple screens and SLI/CrossFire.
