I think specifically the Dell GX270 and GX280 were known to NOT cause problems. I think they may use dedicated video memory, rather than sharing the main memory, and preventing the CPU from having sufficient access. I think these "on board video" problems are really relics from about a decade ago.
I use a GX270 here as my test system, and it works fine. The acid test is just to run the latency test routine from the LinuxCNC menu, and then do stuff on the screen, like start up a browser and watch a video. If that doesn't kill the latency numbers, you are not going to have a problem.
