Honestly.. don't waste your time. We don't have driver optimization for out t989 and NONE of the JB roms run as smooth as they're supposed to. They actually run worse than the best ICS roms with bugs added to boot. I'd give JB another few weeks before flashing. I've flashed every JB rom and whitehawks aokp JB has given me the best experience. But like I said... project butter doesn't even work. I'm not over exagerating. The nexus s with JB runs a ton smoother. We have a ways to go with jelly bean.
