Your 8MB RAM board will be perfect, I used a 8MB A1200 (and a 8MB CD32) for many years playing WHDload games, and even going online and making my own games. You wouldn't want to go web browsing on it (other than maybe visiting Aminet to download more files) but that setup should be enough for just about anything you'd want to do on it.
If you don't want to wait for the RAM board, some games might be playable from the CLI if you boot without Startup-Sequence.
