You won't find an Onkyo 805 unless you are REALLY lucky. The 806 is the outgoing model and the soon to be released 807 will be the current. None of the choices will be all that good at video. Unless your HDTV is 3+ years old, the TV will do a better job up-converting.
What Samsung HDTV do you have? If it is newer I would spend less on the AVR. For great up-converting look for a Onkyo 876 which has a top notch video chip. I highly recommend checking the shoponkyo.com site and become a member (free). You can get refurbished units for less than half of MSRP.
