Interesting you should mention that. I bought a couple of Lenovo Desktops (Vista generation) with two half height slots from the government surplus outlet. I also bought a number of different half height video boards like this ATI RV370 Radeon X300SE https://i.ebayimg.com/thumbs/images/g/phQAAOSwqktdCmjt/s-l225.jpg https://en.wikipedia.org/wiki/Radeon_X300-X600_Series They have the DVI connector on the back and came with a splitter cable with two VGA connectors marked 1 and 2. I suspect they were used on desks with two monitors. All of them, ATI, NVidia, S3 Virge etc. all without exception failed the speed test in LinuxCNC. The motherboard video was always faster. This surprised me. I would have thought that an offloaded video processing would reduced processor load rather than increased it.
