Is there any advantage in a faster CPU and fater ram when it comes to DVD playback at 1600X1200 or 1024x768. I want to build an HTPC for my NEC XG1100 and I only want to scale DVD.... Using an ATI RADEON 9000proWould there be an appreciable difference in playback quality between a Duron1200 with PC133 ram and an Athlon2000+ with PC2100 DDR ram?
