What is the difference between an NTSC and a PAL PS3?? Or does this not apply to this system since it is supposedly regionfree?? I live in North America and use an NTSC system, but might possibly purchase a PS3 that is PAL (from the UK). Would this affect me at all? What do you guys recommend?? Ive read that one issue regarding the PS3 region is the display resolution. I will be playing it on a 1080p monitor. So what should I do??
