How PCs were advertised in the 1990s

I remember almost every one of these ads.

That thing that I remember most is that the ads were aimed at "nerds" and not consumers, so the specs were always front and center. Everyone was really excited when the 486 first came out or the Pentium. Or that there was more RAM or a bigger disk.

Nowadays I'm not even sure which Intel chip is the newest or fastest, nor do I care all that much.
