When I first got myself a REAL video card, I didn't know what AGP or PCI was.

It's not such a LEAP of logic to think someone doesn't know EVERY component of their machine. AND, I can easily see if this person assumed PCI and AGP were simply two different types of cards you could go with.

And no, checking your computer for system parts will not make him a SUN-LESS GEEK. Checking his computer obsessively, and then hopping on a forum and attempting to deride someone for not having "simple" intelligence, in an attempt to validate himself WILL make him one.
