SF3 NTSC on PAL 360?

Hi all

I’m looking to upgrade from xbox to 360 and need some info before I decide to do it. I know that SF3 is now backwards compatible with NTSC US xbox 360s. Wondering if any of you use a NTSC SF3 AC on a PAL xbox 360? (Region free issue + backwards compatibility on a PAL xbox 360)

thanks for the heads up!
