I'm looking to stay under a grand for a new 46-47'' lcd. the 470XVT has come down in price now that the 471XVT is out. Ive heard a few bad things about video processing and artifacting on these so i wanted to expand my options. what is directly comparable to this set? im looking for 1080p and would prefer 120hz. 46'' or 47''. samsung a650 is still quite expensive for its age.. what is somewhat still new that can compete at this price? video games are a high priority for the tv (xbox), it will also be used as a PC monitor.
