Oh, and which card was it that was similarly priced? Oh yeah, the 8800 Ultra, a halo product just like Titan.
You're not comparing apples to apples. Technically, the 680 still is the top end of the line if you're comparing normal, full production volume cards (which all but the 8800 GTX/Ultra were in your list).
Titan is a limited production, limited release product. It's an outlier. It's not part of the regular production stream. To compare it to full production volume cards is what's retarded.
I'm certainly not implying the Titan is the only over-priced product ever made. The 2900XT was over priced as was the 7970 and the 8800 Ultra. Can't really complain about those since the 7970 has dropped in price and the other two don't exist any longer and even though they were all over priced, they were still considerably cheaper.
