According to wikipedia the Falcon 9 has increased GTO payloads from 4,500 kg to 8,000 kg from the 1.0 version to the Full Thrust version. And payload to LEO from 10,450 kg to 22,800 kg.
These improvements have been passed on to the Falcon Heavy, and it's expect to put 64,000 kg into LEO, just shy of the SLS's 70,000 kg.
