Not sure if this is true though...I forgot the name of this "game"
I saw some news about it on one of the MSN/MSFN. Getting 10.1 support for my 3870 while still using WinXP would give me Zero reason to even think about getting Vista.

Last review I saw showed a 3870 doing pretty good with 10/.1. Beta tested by some guy.

DirectX 10.1 in Windows Vista SP1 – The Evolution - Under the hood
Posted by xper on 31 Oct 2007

As Windows Vista brought to the table the exclusive DirectX 10, the first service pack for the operating system will evolve Microsoft's graphics technology to version 10.1. DirectX 10.1 is already available to over 12,000 testers via the first beta of Vista Service Pack 1, concomitantly with the official release of Build 6001.16659. Although the testing milestones of Vista, Windows Server 2008 and Windows XP SP3 Beta, are officially limited in terms of access, a hack is available designed to permit the download of Windows Vista SP1 Beta Build 6001.16659 straight from Microsoft, and simultaneously test drive DirectX 10.1.

However, Vista users have to understand that DirectX 10.1, as well as DirectX 10 is a technology intimately connected with the underlying graphics card, such as the upcoming ATI Radeon HD 3800 Series. According to an AMD whitepaper focused on the implementation of DirectX 10.1 in the ATI Radeon HD 3800 Series, the latest application programming interface from Microsoft, manages to "unlock the state of the art in GPU technology."
Sure the OS has a lot to do with it.
