Im looking to make a computer and i need help

I was wanting to play starcraft 2 and i was wondering if these specs would be good to play on like ultra? medium or what and how good fps? My max budget is 500$ and i went under with a total cost of 485$ so i really like this but i want to know if it is good enough?

An will this all fit together and work properly?





How about this combo?
