I have a friend looking to upgrade his old 400 MHz system. It has a DVD drive that currently doesn't work for movies cause he needs a hardware decoder to hook it up to (he has a TNT video card). I thought I saw somewhere that newer CPUs (over 500 MHz) don't need seperate hardware decoders. Is this true? If he were to buy a GeForce 2/3 would he be able to watch movies from his current DVD drive? Are there any special cables/connections required besides the IDE cable, and sound card connection? What about special software? Thanks.
