At the moment the best and only high powered 3D card option for the A1 board is the ATI Radeon, and one of the cool toys that A1 owners with HDTV (digital TVs with a 1080x400 screen resolution) can look forward to is the new Radeon 8500 HDTV component adapter.
This has got to be the coolest TV Modulator ever..
