Because it's not all about rich people willing to throw money down the toilet on technology that will last for six months at best.
Cheap stuff sells in higher volumes. Look at the Steam GPU chart, at the top was the GTX 960. Having *that* card is what makes you money, not ridiculously priced (and named) items.
Hopefully they have tweaked it a little and made it as good as, or better, than the 970 and 980. That's what they're gunning for with the 300 cards. The Fury will take on Titan but no doubt cost millions to make and thus will carry a stupid price tag.
When they're £300 each or less I'll pounce, until then I just wait.
Stop being reasonable, thats not what this thread is about
