I have an IBM Aptiva Pentium III running at 933MHz with 256Mb of RAM and an N-Videa video card with 32Mb of video memory. I want to replace the video card with one of the Radeon AGP cards with 128Mb of video memory. I don' run a lot of video games on my computer but I do some other video based stuff and watch some DVD's on it. A side note.... For the longest time, I have noticed that my DVD playback is atrociously slow and choppy. I recently had to replace the DVD drive for mechanical reasons but this did not improve it. I checked the settings in the hardware and software and Power DVD etc. I also have Mediamatics and Interactual DVD software. I will try a search for another thread I posted here months ago on the DVD playback.
