4 for everyday use....2 for benching. As to whether or not to keep it for benching depends on how it overclocks, obviously. It's really about what you want and need. If you only want to use it for everyday use and I works fine then keep it. If you only want to overclock it and it clocks well then bench it then get rid of it.. RMA chips aren't always bad clockers.
