We have heard about the following card from OMNICOMP:
Maybe somebody has experience with it ?

3DEMON 3-D Graphics Accelerator for PCI Local Bus
Technical Brief
-----------------------------
The 3DEMON provides workstation class 3-D graphics and high performance
2-D acceleration using the GLINT (tm) 300SX 3-D processor from 3Dlabs.
The 3DEMON accelerates all rendering operations of OpenGL, including
Gouraud shading, depth buffering, fogging, anti-aliasing, alpha blending,
scissor and stipple mask, dithering, and logical operations.

Features:

* 3-D rendering acceleration
* 64-bit GUI acceleration
* Texture mapping acceleration
* Z-buffer for hidden line/hidden surface removal
* PCI 2.0 compliant
* 100% OpenGL compliant

Frame buffer:

* 4 Mbyte high speed VRAM
* 8,12,16, and 24/32 bits per pixel

Local buffer:

* 4 or 8 Mbyte DRAM
* 32 bits per pixel contains Z-buffer, Stencil field, Fast clear
control, and Graphics ID

3DEMON Model SX44

* 4 MByte frame buffer, 4 MByte local buffer
* Double Buffered Resolutions
800x600 24/32-bit (3-D)
1024x768 16-bit (3-D)
* Single Buffered Resolutions
1024x768 24/32-bit (3-D)
1280x1024 16-bit (2-D)

3DEMON Model SX48

* 4 MByte frame buffer, 8 MByte local buffer
* Double Buffered Resolutions
800x600 24/32-bit (3-D)
1024x768 16-bit (3-D)
1280x1024 8-bit (3-D)
* Single Buffered Resolutions
1024x768 24/32-bit (3-D)
1280x1024 16-bit (3-D)

Performance:

* Up to 300K* , 24-bit, Z-buffered, Gouraud shaded, alpha blended,
25-pixel triangles per second
* 1M* 10-pixel vectors/sec (24-bit)
* 500K* 10x10 rectangles/sec (24-bit)
* 5-10x performance increase for OpenGL applications
* Up to 10x performance increase for bilinear texture mapping
(*) platform dependent

Software Compatibility:

* Hardware accelerates Microsoft's implementation of OpenGL under
Windows NT (tm) 3.5 and Windows 95
* 2-D drivers (included) for Microsoft Windows 3.x, Windows 95, and
Windows NT 3.5
* HOOPS, 3DR, and other industry standard 3-D APIs
* Reality Lab, RenderWare, BRender, and other 3-D games APIs
* Accelerated-X drivers for The X-Window System by X-Inside
* Microstation, Caligari trueSpace, Sense8 WorldToolKit, and
OpenInventor
* Support for AutoCAD and 3D Studio is under development

Hardware Compatibility:

* Minimum OpenGL platform of Pentium processor, Windows NT 3.5, and
32MB RAM recommended
* Windows NT 3.5 support for PowerPC, MIPS, and Alpha processors is
under development
