OK, using those Reddit perf results, the 470 would be 1.12 * 380 perf. New 380s on OcUK right now are £150 (or £80 2nd hand).
That means for the 470 to be *worse* price/perf than a 380, it only has be £168 or more.
Given Gibbo's "much more" than £150 comment, then the 470 is *quite likely* to be *worse* price/perf than a 380.
We can only hope I'm totally wrong, but this is the situation we find ourselves in going by the leaks and Gibbos comments.
No, but stagnating the mid-range won't help them sell products, either. Eventually, people on ultra-low end cards will all have upgraded to 380 or 290 perf, then what will AMD do, when they can't release another card with the same perf but lower power?
