Because of something that costs more can easily be acheived by a regular one. Also they share the same architecture and all that is changed is base clock, the max frequency is still the same

Ghz bios is fubar. Well, for the normal user it doesn't because the ghz bios starts them off slightly higher clocks and you get boost. But for the enthusiast it just gets in the way and we don't need locked volts even if the limit is slightly higher. I would have to undo the ghz portion before I got into serious overclocking anyways, so it's a waste of money for me.

If I remember, there is a button on the backplate that activates it, and enthusiats can afford to open their desk up etc and slide their pc out just to click a button

GHz cards come with a locked voltage BIOS so you have to flash it before you can do any voltage adjustments. Also, you're paying more for a card that is pretty much exactly the same.

So by that logic... I could buy a GHz 7970 from XFX, flash the BIOS, and then I can overvolt the card?

My MSI R7970 Lightning GHZ is damn good, fully unlocked on everything, the amount of adjustments you can make in Afterburner on the voltages, power limit and clock speeds is amazing. Well worth the price.

If the current generation of 7970's are anything like the 7870's from xfx they will be voltage locked. I think you want the very first xfx ones if you want unlocked voltage. My XFX Black 7870's are both voltage locked and purchased around 11/2012. They even cheapened the cooler design to use less copper and not cool the vrm's on mine.
