Car got hot twice, think that I have a blown motor, warped head or maybe just a head gasket?

About 2 months ago my water pump went out, when it did the car got hot very quickly and shut down. We have since changed the water pump and one day ago the car did the same thing, got hot quickly, shut down, only this time it will not start. It spins and when I had the raidiator cap off and tried to start it water came spewing out bad from the raidiator, when I put the cap back on it showed me that my raidiator had holes or it blew holes in it. When I crank it it sounds as if the motor is just spinning, not clicking like a battery would do. I only paid 80.00 bucks for the car in 2009 and have only had to replace the starter, altenator and the water pump, but I don't know if it will be worth it, car was running great before this really good on gas and it got me from Pennsylvainia to Arizona with NO problem.
