If you had to add quite a bit of coolant you may have an air bubble in the engine which will cause it to over heat quickly. What you can do it jack the vehicle up on the side of the car that has the highest access to bring the bubble to the top. Or you can run the vehicle at idle for a while with radiator cap loose or off.
Also when you replaced the gasket did you use a gasket sealer? If so you may have gotten some on the thermostat and it could be stuck closed.
