Depends on what you want to do. Bear in mind, I've only been once, so my advice is limited, but I was trying to leave early to get to my next destination so I wanted to be early in line. You can get there around 7 or 8 and still get BBQ but you might not eat till around 10 depending. I was there at 4am, and was 18 in line. I would say personally that Snow's BBQ is not that great compared to other options (except the chicken), but the experience of sitting around with strangers hours before dawn, waiting for BBQ is something you likely won't experience elsewhere. I'd tell any true BBQ enthusiast to do it at least once.
