I am in the process of selecting components for a home built computer and am in need of some technical advice. If I choose a DVD device instead of a CD-ROM, should I get one with a hardware decoder card? I have no intention of watching DVD movies since my VCR works fine, the recliner in my family room is much more comfortable than my computer chair, and my computer is nowhere near my TV. However, I do like high power games (on my monitor not on my TV). Do these games make use of the decoder card in the same manner as DVD movies do?
