DX10 and Current Graphics Cards?

[nands]

I was wondering if anyone knew how current graphics cards will perform under DX10?

Obviously we know that DX10 is a complete rebuild of the graphics software but will current hardware be able to take advantage of any of it, or will a DX10 configured graphics card be required? Basically how much of DX10 is software dependant and how much is hardware dependant?

I would like to hear your veiws.

You will require a DirectX 10 compatible graphics card to use DirectX 10, no current card will do I'm affraid. You will also require Vista if you want to play games in DirectX 10 mode, as the Windows 2K/XP support dies with DirectX 9.

Additionally, many here will suggest waiting a few months after Vista is launched until more DirectX 10 titles appear, as the first wave of DirectX 10 compatible graphics cards will probably be replaced by then.

It looks like top end gaming next year will be an expensive exercise! I assume that all of the DX10 games next year and for quite a while will have DX9 support.

I will be interested in knowing what performance/quality gains are running the same game under DX10 compared to DX9 (obviously with as similar hardware as possible).
