DirectX 10 enabled on W7?

[Granite]

Hey guys, im considering buying a new video card, but atm they are all manufactured DX10. Is it possible that they can be enabled DX11 on W7? without waiting throughout the whole year for these cards to release, i need a new card badly! Any answers will be great!

ATI 4800 series cards have preliminary DX11(DX 10.1 being mentioned) support..... they support all new API features which comes with DX11 except tesselation which has only partial support. I checked that out using DX11.
All cards which are 9.0c+ certified can run windows 7 with DX11 but the new features won't be supported on any card which is DX9.0c and DX10 certified. DX10.1 is your best bet now which is almost similar to DX11.
None of the nVidia cards support more than DX10...but they will work fine on windows 7 too only newer features won't be accessable...that's it.
If you are so into CUDA....CUDA my friend is about to come down atleast for the non-professional arena....DX11 introduces a new feature called WARP and GPGPU-Processor which will enable non-graphics processing on ANY gpu like physics etc...this feature will run on DX10 and DX10.1(obviously).
So you can obviously go for nvidia....but ATI 4800 series is more sorta future proof....pure DX11 cards are gonna come from nvidia and ati both but they will come after June 2009...so you have to wait. Microsoft is working with ATI on the GPGPU feature....
However the most powerful GPU in the market is nVidia GTX295 but it is still DX10.
Hope it helps
