Sniffle, sniffle,  the only RAM my motherboard takes are PC 600 or PC800's-an Intel (Lexington 2 motherboard).  The cost is around $300 for a 512MB RAM kit ( two crummy 256MB RAM chips).  So to get more RAM is a new motherboard, a power supply that is not 250 Watts etc and I'm not a do-it-yourself-installer (too many little pins on the CPU and it only takes one fold over and the CPU is hosed, or smash the power supply on the motherboard or not get the CPU heatsink properly coated with heat transfer paste and seated properly on the CPU etc.

By the way, it appears that you bought yourself a coprocessor video card and not an accelerator type.  Your co processor card is designed specifically for CAD, 3D studio, Maya etc-it allows your main CPU to do other things and not share its time with graphics.  

I certainly would be interested in how it functions with all your software 3D programs.  Plutom
