Yeah, I was mostly highlighting it here for the audio part, which, in my head, is a little bit wiser then going all out on video. People these days have old video cards still and a lot of people are still in the process of realizing it's time to upgrade (I blame all the recent game releases). But something almost everyone has is a speaker/sub woofer system. Making something look good is only half of the battle.. sound is pretty good to have to.
A friend of mine just bought a surround sound system for his computer so he could play Mass Effect. It's pretty damn cool.
