I need a recommendation for a ATI graphics card including part numbers to go into a power PC

This graphics card will be connected too 3 widescreen samsung tv's.

2 screens will be linked togethor and one will be a standalone.

The right graphics card needs to have:

compatibility with widescreen TV's running 70p/1080p thru DVI/HDMI connections

Twin head outputs in DVI to run two seperate web page applications too seperate TV screens

1920 x 1080 screen resolution with resolutions greater
able to handle 100mhz refreshes

Clear crisp fonts

enough memory to actually run smoothly

I Need a solution which is powerful and does what it says on the tin, with drivers for Windows XP.
