Very useful -- more please?
This is a topic that could use more comprehensive, systematic, and regular, attention. Say, twice a year -- once before the Black Friday/Christmas/Boxing Day shopping season, and once somewhere around July?
One additional quibble -- non hardware-junkies (like myself) would benefit enormously from a little more detail and backround than "modern GeForce 400 "Fermi" graphics cards and newer" or "Radeon HD 5000 graphics card or newer" or even "any GeForce 9+ GPU". Not everyone keeps track of all these things, especially if we only have one or two computers we're mostly happy with.
Aside from that, I found this very useful and informative.
I bookmarked the article before I was halfway through it.
