Summary: I'm running two of these in a linux box (Scientific Linux 6) and am having absolutely no problems with them. They just run X, no games or anything and, yes, on the date I write this the 5830 is yesterday's tech. However, given the price of these versus a 6990, these give a little more GPGPU crank per dollar. I'm running OpenCL accessed via python (pyopencl). I switched from CUDA to openCL because openCL is, well, -open- and runs on more hardware.
