No, i think all G400 boards used a maven chip for the second head, well,
actually it is not a separate chip, but included in the G400.
The G450 was a G400 with a smaller process and which used a DDR memory
bus instead of the dual mono directional SDR memeory bus of the G400. I
think it was more or less the same, just cheaper for matrox to
manufacture.
