This card is the second-fastest single-chip card in AMD's Radeon HD 3000 line. The particular PowerColor unit I have differs somewhat from the AMD reference HD 3850 card as it wears a relatively noisy but effective two-slot heatsink instead of the reference single-slot one and has GDDR3 clocked at 700 MHz (1400 MHz effective) rather than the default 828 MHz (1656 MHz effective.) It is supported well by AMD's proprietary fglrx driver and has 2D support at the moment with the Xorg "radeon" driver. The video decoder is not supported at the moment under Linux, although the UVD2 in the Radeon HD 4000 series is supported by XvBA and accelerates MPEG-2 and H.264 playback.
