[?] Best performance ROM for G-Tab with GPS support!

its been too long, now i want to revive the G-Tablet and i tried DHR HoneyComb, Dirty Bean a while back, but HoneyComb webcam/mic does not work and dirty bean is jsut too slow...

does anyone can make suggestion the best performance and hardware support ROM?

P.S. if 1GB ram upgrade works, it might help dirty bean alot!
