An 8 gallon pot will not work for larger (1.060+) beers, go with a 10 gallon minimum or better yet a 15 gallon pot from the beginning and save yourself the hassle of managing the boil overs, upgrading in a few months, etc.
I do not recall from your post, but I assume you are brewing inside, if so 8 gallons might be all you can bring to a boil on your stove.m When I moved to brewing outside with propane, I upgraded to a 15 gallon pot. With this size pot I've brewed 1.10 size beers and absolutely love it.
