How much silver can I expect to earn per day on GammaNow with a 5700 xt?

I need some extra silver and figured GammaNow would be the easiest way to get it. I currently have a 5700 xt which gets 50mh/s mining ethereum (which i assume is what gammanow mines too). How much silver can I expect to earn per day with that card? Mining eth gives me 0.0013 eth per day, so around 3.5$, I guess that should be around 3k razer silver per day. Anyone know for sure what I can expect?
