The only risk of trying should probably be the PSU. If it can't handle the graphics card, in the worst case you might just brick the whole system. Other than that, there shouldn't really be any danger in trying it out. Worst case, it won't work, I think. That is, unless old systems had more ways to break than modern ones, but I can't imagine any such ways.
