I will just quote from a pc magazine (PC Format I bourght last month..
The DX10 Debacle continues Mindless API update makes DX10 cards obsolete -What are they playing at?
Microsoft has announced that Vista SP1 will contain Dx10.1 - an update to the much critizised API that has already bourght £500 gfx cards to their knees with frame rates a shadow of those achived under DX9.
However, the new version of Direct3d - the graphics rendering component of DX10 - doesnt just make cards such as Nvidias 8800 series and Ati's HD2900xt series huff and puff; it renders the obsolete. Yup you heard right; the latest DX10 hardware wont actually be compitable with the update. And its an update that the two crucial parties in the gaming industry - developers and gmaers- will care little about. Among other things, it will actually enforce x4 AA which is crazy talk if you consider that many people running 8600gt and the likes. It's quite insane. Developers already face a difficould choice- why should they pour cash into developing games in Dx10 as it stands?
*skips Editors rant*
Perhaps patching the development tools/partially developed games will be a smooth process? You can never tell with M$. Video cards that support DX10.1 are coming out now though. The Radeon HD 3000 series (already out) supports it, and the updated nvidia 8000 series supposedly will.

More reason to put off buying a new card. I'll probably wait to see what nVidia brings out in the Directx 10.1 line. The 3850 is looking pretty nice though...
From the first articles I've read about DX10.1 is that it's just an API upgrade. Your 8800 GT/GTX, whatever will work just dandy on DX10.1 applications, but you're missing out on [varies greatly] 1-20% performance. Why 10.1 is coming out now instead of back then I don't know, but from what I've read and heard [one of my relatives is a hardware analyst, been in the industry for a long time], it's not really a big deal.
Is directX 10 just for vista or also for xp?

There have been rumors that Microsoft will eventually release DX10 for XP, but as of now that's all they are - rumors. There is also a few teams out there trying to engineer their own version of DX10 for use on XP, but that may be a ways off - if it ever happens at all. In the mean time, if you absolutely have to have DX10, you absolutely have to have Vista.
IMHO it's not DX10 vs DX10.1 so much as whether MS will continue to make their future DX updates exclude the current DX10 hardware. Comparison screenshots and testimonials have indicated that even when comparing DX10 to DX9 in Crysis for instance is not a significant difference. I tend to think it would be even less between DX10 and DX10.1. However if the next builds improve further, especially in the form of more new shader models beyond 4.1, it may start upsetting the current DX10 hardware owners if they continue to be left out.
Current DX10 cards will run be able to run games that require DX 10.1. Is just that they wont be able to take advantage of the new API offered with DX 10.1. Theres nothing to worry about for the fact that the new API in DX 10.1 isn't something thats going to make game developers base their games on DX 10.1 for quite sometime. The new API doesn't add anything thats major. Current DX10 cards are not obsolete.
