Well. I will disagree with Ofer on this one. Depending on the output resolution you choose, you could indeedy lose sharpness. Many of the processors listed above lose sharpness at some point slightly over 720p. I have seen several HTPCs which are razor sharp at 960p or 1080p. BUT, sharpness isn't everything. Various deinterlacing methodolgies give up sharpness to get rid of jaggies and other unpleasant creatures. Some HTPC lovers say wow, my HTPC is sooooo sharp and your processor isn't, but their deinterlacers suck. Still all in all, many processors can't cut it re sharpness above 720p.
