Can a low-end DX10 card run all DX 9 games?

[executioner]

Hi,
I wanted to know if an entry level DX 10 card run all DX 9 games?Can it do that at the highest setings?Will a low-end DX 10 card be better than all DX 9 cards(even 7900GTX or may be 7600GT)?When will ATI release DX 10 card?

We know nothing until it comes out.

I don't think there will be any 'low end' DX10 cards any time soon. The first DX10 card will most probably be the 8800GTX and i don't think it'll be any where near 'low end'.

and yes all the DX10 cards will play all DX9 games pretty decently afaik.

here's some info on g80:

As if we mere mortals needed more reasons to be excited about G80, here are a couple more tidbits: 128-bit high dynamic-range and antialiasing with 16X sampling.

The high dynamic-range (HDR) engine found in GeForce 7950 and Radeon series graphics cards is technically a 64-bit rendering. This new HDR approach comes from a file format developed by Industrial Light and Magic (the LucasFilm guys). In a nutshell, we will have 128-bit floating point HDR as soon as applications adopt code to use it. OpenEXR's features include:

Higher dynamic range and color precision than existing 8- and 10-bit image file formats.
Support for 16-bit floating-point, 32-bit floating-point, and 32-bit integer pixels. The 16-bit floating-point format, called "half", is compatible with the half data type in NVIDIA's Cg graphics language and is supported natively on their new GeForce FX and Quadro FX 3D graphics solutions.
Multiple lossless image compression algorithms. Some of the included codecs can achieve 2:1 lossless compression ratios on images with film grain.
Extensibility. New compression codecs and image types can easily be added by extending the C++ classes included in the OpenEXR software distribution. New image attributes (strings, vectors, integers, etc.) can be added to OpenEXR image headers without affecting backward compatibility with existing OpenEXR applications.
NVIDIA already has 16X AA available for SLI applications. The GeForce 8800 will be the first card to feature 16X AA on a single GPU. Previous generations of GeForce cards have only been able to support 8X antialiasing in single-card configurations.

This new 16X AA and 128-bit HDR will be part of another new engine, similar in spirit to PureVideo and the Quantum Effects engines also featured on G80.
