This item is from the PC 3D Graphics Accelerators FAQ, by Blair MacIntyre with numerous contributions by others. (v1.2).
The PowerGL card is the Accelgraphics AG300 being sold OEM by ISC, which is described above. Since the AG300 and the PowerGL are the exact same card, I won't repeat the specs here. Talk to both companies, see which one better suits your needs.
