San Francisco is ridiculous. At $50k you are either going to have 2-3-4 roommates and probably still have to use BART to get to work since you won't be close, Or live in the east bay or Oakland and have a 10-20 minute drive to a BART station and then another 45 minute train ride. Any studio that would offer $50k would know that is not a very livable wage and it is probably looking to take advantage of people trying to break in. Driving in the city is horrible and I would only do it if I had no choice.
Is there any reason you want to move to San Francisco? Midwest has some game studios and the cost of living is much more reasonable. West coast has droves and droves of people looking to get in the industry and they are already here. You are going to have to have quite a bit of a nest egg to make the move since it could be months before you even get a job (or ever). You can probably take a part time job at fast food or something to help with the bills but that is time you can't spend looking for a job or making your portfolio better.
