I have a GTX 780 Ti Classified. It's not listed on the eligible cards list. I bought it directly from EVGA. Is it eligible for the step-up program or not? 
I haven't seen benchmarks comparing the Titan Black vs 780 Ti Kingpin vs 6GB GTX 780. The current step-up appears to be for the non-Ti version of the 780, with 6GB as the differing feature. 

I look at it like this Maxwell is probably going to be late to the party this year. My guess is they are having issues getting the die shrink down to the point it will be profitable.

Just found out about this. My card qualifies. Nice!

Looks like it's true.  
 
Kingpin & Classy will also be getting 6GB. 

If its true then how will this affect the Titan Black if the Titan Black is pretty much a 780 ti with 6gb?

That's expected I told NVIDIA didn't finish with GK110...
But bad thing is because even 3GB and 6GB in same time I couldn't afford K|NGP|N with 6GB memory.
Selling K|NGP|N Edition for 765e in Europe was so good for me because I had literally on edge with money.
I waited only one more complication to talk with friend to gave-up and order GTX780Ti Classified, but than again with backplate I would be with 35e in pocket at the end.
 

So I'm guessing there's no step-up available for K|NGP|N owners when it gets the 6GB?
 
Jacob Please confirm.
 
Thanks.

Good question, titan black will still have double precision (FP64) for compute going for it unlike the 780ti.

Will this work with the 780 Classified HydroCopper?

I doubt more than 5% of people will even think on Titan Black over 800$ if any GTX780Ti model over 3GB show up. 
Even reference model of GTX780Ti. Ti will be faster, cheaper, same memory. Better shopping for gamers.
Maybe some very very rear specific situation and for lot of less money than now. 

Perhaps too early but would love to see some indication of price for 6gb 780 Ti now that we have seen a price for the 6gb 780 ($550). Pure guess but I'm thinking maybe $800-$850??? Or small price drop of 3gb 780s ti in order to make way for their 6gb counterpart priced near the 3gb version's original price (wishful thinking).
