1. Well, DUH. What, you just figured this out? And you assumed this "revelation of information" would enlighten us all somehow? Believe me, this is OLD news to 95% of us on this board. Take a look at the majority of discussions, and you'd realize we either A.) Want a kick-ass video card "just because" (not because we "need" it), or B.) Actually NEED a kick-ass video card because our job/hobby/etc. *required* it.
2. Tom's Hardware is not a "premier computer information site". It's actually heavily biased, but I won't go into that here. Tom's is considered a good REVIEW website.
"Integrated video is fine for most" was old news in 2000. Try to keep up.
