Moses Posted October 6, 2008 Share Posted October 6, 2008 Ich würde eine 4650 vorziehen, wenn HDTV im Spiel ist. Da wird's bei den schwächeren für die besseren Deinterlacer einfach wieder nicht reichen. Quote Link to comment
converge Posted October 6, 2008 Author Share Posted October 6, 2008 Deinterlacing ist das Stichwort. Wäre mal interessant zu wissen, ob es mit ner 4550 möglich ist 1080i Material vektoradaptiv zu deinterlacen mit nem Zweikern Prozessor, sprich AMD 4850e auf nem 780G Board. Quote Link to comment

Da sind wir ja schon zwei, warte auch gespannt auf einen aussagekräftigen, fundierten Test. Siehe Hier Quote Link to comment
