I've been suffering from the same awful tearing problems, and forced Vsync in Catalyst Control Center is notoriously useless with most games.

Odds are we're stuck holding out until the new graphics engine and hoping it either doesnt have tearing issues or has in-game vsync support

I've read a few old reports of people using MSI Afterburner to replace the CCC and using that to force vsync with more success, but it's not exactly a supported tool and is mostly used for overclocking (so you can do some serious damage if you misuse it).
