Yes and no. Most HDTV tuner cards are software based. Your CPU wouldn't be capable of decode an HDTV signal and audio at matching time. You may be able to at lowest get digital broadcasts though (still looks sharper than regular TV). Most stations that broadcast HDTV also broadcast standard digital alongside it.
