7870 works fine with 120Hz if monitor says it supports it. It's quite misleading to say "AMD doesn't support 120Hz" without qualifying, when in reality the case is that AMD doesn't let you run out of manufacturer's advertised spec without hacks, while nV makes it easier for those people who know (or think they know) what they're doing.Well there's a hack or something that "supposedly" works. 100hz is it.chimaxi83 said:Huh? AMD doesn't support 120 hz? That's news to me
