Why do you say that? The 7970GE edition is re-establishing the $500 price point for AMD, and as soon as the hd7950 is all but out of stock, they'll replace it with the 7950GE edition for $399, once again raising the price. Unless no one is buying video cards this summer and fall, prices aren't going to drop much. Expect to see Nvidia start bundling games with their gtx600 lineup before they drop prices.
I am not sure that's how it will work. I think AMD sells AIBs 2 separate binned chips. They can either buy the pre-binned HD7950/7970 GE editions or stick with the original ones. So I don't necessarily think HD7950/7970 cards will be discontinued any time soon. The original 7950/7970 chips will just occupy lower price points ($300-320 / $400-420) while the GE cards will have a $50 premium on top of that respectively.
Neither Newegg nor Amazon has a single official 7950 or 7970 GE card for sale yet despite 7970 GE's official launch almost 1 month ago! Perhaps AIBs don't want to pay a premium for the XT2 chips.
Maybe AMD should have launched HD7950 GE as 7960 and HD7970 GE as 7980. From a marketing standpoint it would have made a lot more sense imo.
HD4870 = 750mhz GPU / 3600mhz Memory
HD48
90 = 850mhz GPU (+ 13.3%) / 3900mhz (+8.3%) Memory
HD7970 = 925mhz GPU / 5500mhz Memory
HD7970 GE = 1050mhz GPU (+13.5%) / 6000mhz (+9%) Memory
IMO, AMD marketing dropped the ball again...They could have claimed the fastest single-GPU in the world title with the HD7980. Instead the average gamer probably clings to launch GTX680 reviews where it clobbered a stock 7970.
