Those cards support OpenGL 4, but do not support OpenCL, unfortunately. My previous computer, now sitting unused in a corner, has an EVGA GeForce 210 card in it that supports only OpenGL 3.1, according to the box it came in, but does support OpenCL, though it doesn't say up to which version of OpenCL. The modern x11/nvidia-driver does not support this older card, but x11/nvidia-driver-340 does support it. I could pull one of the Radeon cards, disconnecting the unsupported-by-X.org Crossfire cable, and replace the card with the EVGA card if the older driver it requires supports OpenCL on it. Can anyone tell me whether it does? If so, I would like to leave the monitor connected to the remaining Radeon card and use the Nvidia-based EVGA card just for OpenCL. I would rather not spend money on a newer and more powerful card from either company just to familiarize myself with OpenCL, and the EVGA ought to be good enough for that purpose if the driver will support it. Thanks in advance for any information on this! Scott Bennett, Comm.
