That doesnt prove any point. The card is for anyone who wants it. I dont think eVGA specifically sat down and said lets make thousands of these cards and sell to the rich kids that we see once in a blue moon. They said hey lets take the design we use on all cards and do the same with the 8800 series.
The ENTIRE point of SLI is to sell 2 cards when previously they would only sell 1. The point of "Directors Cut" is to get the extra $10 out the moron who is willing to pay for it. "XXX edition" and "SuperClock" are ways to get extra money out of dumb people. EVGA isn't your best friend looking out for you. They are there to get every penny out of you. If they can find a way to sell the EXACT same thing to you for $30 more, you better believe they are going to do it.
