Matrox G200 quad v's G450 quad

Looking at adding another card to my second PC to drive some monitors to display guages.Anyone used either the G200 or G450 quads? The G450 initially looks better because of the newer GPU and the 32MB of video RAM per output as opposed to the 8MB per output of the G200 but the G200 quad uses four G200 GPUs, i.e. one for each output as opposed to the single G450 GPU covering the four outputs.Not sure if it would make any real difference for displaying guages anyway but if anyone has compared the two then any input would be appreciated...Thanks.
