Thanks for dropping by, folks.
I just upgraded my system from T-bird 1.2 GHz, 1G PC133, and ATI 8500 to Athlon 64 3200+ venice, 2X512M dual channel, and EVGA 6800GS. I was planning to mainly use this system to watch 1080P movies and play a little bit games.
I set my new system up a few days ago and fresh-installed OS and all the drivers. I have not tried any games but a lot of video playback. But I am very dissappointed at its video playback quality on my 37 true 1080P LCD monitor.
When I played any DVD or Divx files of the same quality level(640X480), I found out that the quality of the picture was not good. Color was neither pure nor sharp. Basically, the picture quality is nothing comparing to my old (slower) system.
When I was playing 1080P content(Which my old system can not play), there were two problems.
1: The pictures were dark and grainy. Also the pictures were not sharp as you would expect for a 1080P level.
2: the playback is not totally smooth. I could see that some frames were skipped. Initially, I thought it was the lack of CPU power. But when I looked at the CPU usage, it only used 60% of the CPU power.
The other thing that I should mention is that I did not upgrade my IDE hard drive because of the budget and some reviews said that there were just very small performance boost from IDE to SATA. But my drive is 7200 RPM. When I tested it, it could transfer files at about 80 MB/second.
My questions are:
1: Is my IDE harddrive the bottleneck of my rig? Leading to the slowdown of 1080P playback.
2: Is my shift from ATI to nVidia a really bad move as far as video playback is concerned?
Thanks again, any input is welcomed.
