ok i realised a little while ago that DX10 is coming out when Windows Longhorn does (i no its called Vista but i rekon Longhorn is much cooler) and i was wondering if only the latest cards that come out wen DX10 will be able you use it. Im getting a 6800GT soon and will probably buy another for SLI and i dont want to get 2 6800GTs and then find out that the games that use DX10 wont run on my system.
