I have new MacBook Pro (with Thunderbolt) and a relatively recent Windows desktop. I'm considering buying the new Thunderbolt Display to replace my Dell 2407 LCD. Can I use the Thunderbolt Display with my Windows desktop? My Windows box has a 2009 Nvidia 260GT video card, but I'm willing to upgrade that card. I know that the Apple Cinema Display with Displayport can be used with a Windows box (but may require setting the brightness first on a Mac).
