Unless your buying new videocards every 6-12months waiting for a 8970 would be the most logical thing. AMD cards are currently spot on with Frame Times using one card beating out Nvidia on many titles. CF should be fixed soon allowing AMD to have great drivers for the 8000 series.
If you can pay the same amount for the GTX780 to get titan performance then why not?
Personally Q3 would work out good for me as I'm going to buy all my new haswell gear first then get a new card/block. Hoping to see some good WCing OC.

Why not? 28nm is very mature as it is right now. It's possible to spin out such a chip. So using your statement Richland would be impossible to have the 10-15% gains? With less power consumption than A10-5800k (not that it had alot, it was surprisingly close to a i7-3770k in the first place) Now, GCN2.0 is alot more efficient and clocks alot higher than GCN1.0
The 7790 which is from GCN2.0 has just 40% more shaders than 7770, clocked higher at like 1.075GHz and has performance considerably much much above 7770 and uses not much more power. Alot less than 7850. But a 7850 will clock nearly 50% (than stock) more when OC'd just like 7950 would do so. I expect GCN2 to be very similar in OC'ing performance

It's called being overkill necessarily. Kepler doesn't scale well beyond trifire because of it's natively tiny bus. And also seems like AMD likes larger buses now. Yes it's more complex but when we begin to use 4k displays you will know why AMD wants to. Why design a series for trifire and quadfire if they will get bottlenecked by the memory bus? AMD knows what they are doing as they have done this mistake before but it wasn't needed then i guess.
384 bit bus + 6GB? FTW! But what's wrong with 384-bit buses? It's not like tahiti doesn't have one. When it comes to boosting memory bandwidth there's two options : Increase the bus width OR Make the IMC run super-fast and have to use highly binned chips

I thought cards were supposed to get faster as time went on...Correct me if I'm mistaken somehow.
Whoever counts using transistor count is hopeless ... GCN 2 is alot more efficient. This is NOT GCN 1.0. Just like HD7790 is phenomenal for it's power draw (It's from GCN2.0) we can expect some surprises here and then. 384 > 256. But if the IMC can handle 1.75GHz GDDR5 then so be it, it doesn't need 384 then, i guess.
Maybe 256 is not accurate. I can't see AMD using a smaller bus for a newer card than the one it replaces. It just isn't logical

Core for core GCN2.0 is quite the bit faster and more efficient than GCN is

But then again nvidia did the same thing as AMD is doing now right? They released the gtx 480 later which then with the gtx 580 also beat the 6970.
With 100W more power consumption if that's what you want. Nvidia prices never go down and that's in the books of history

That's Volcanic Islands which is in 2014, i think. But definitely going to be the HD9000 seriesEdited by DaveLT - 5/28/13 at 10:42am
