>comparing AMD OC to Nvidia stock clocks
You like doing that a lot.
The 560 Ti was a fine overclocker, it was cheaper, and the point remains that it was a respin of a chip that released at $200 twenty months earlier. So, outside of the memo field of cheque made out by AMD, I have no idea where you're getting that it is a "nothing" that somehow put Nvidia in dire financial straits.
You clearly keep living in alternative reality. When 7850/7870 launched, 560Ti and 570 became irrelevant for 6 months stock or OC vs. OC.
I even specified in my posts that 560Ti OC only dreamed off catching a stock 580 while 7850 did it easily while after-market factory pre-overclocked 7850s traded blows with
more expensive 570. I never compared 7850 OC to a stock 570. Also, the lack of VRAM made 560Ti/570 irrelevant for someone intending to keep the card for 2-3 years even though NV fans fought this notion. In hindsight 560Ti/570 were 'junk status' if you had forward vision because now you can't use them for anything really with VRAM bottlenecks. With AMD and NV now having 3-4GB cards in the $180-350 range with 280/280X/970/290, 680/770 2GB are next cards to become VRAM bottlenecked. At least you can still game on a 7850 / 7870 2GB OC today but those 560Ti 1GB/570 1.28GB are paperweights. You also focused entirely on the price and didn't even talk about power usage where Fermi got owned just as bad against GCN as 970 owns the 290.
7850 nearly matched a 570 while using
100W less power and having 2GB of VRAM, and overclocking ability to beat a 570 OC. And of course bitcoin mining that made 570 completely irrelevant for 6 months for anyone but the most devoted NV fan because the 7850 made $.
The point you keep missing is that 7770/7850/7870 utterly destroyed Fermi in features, performance, overclocking, VRAM per $ and multi-monitor features for 6 months straight but NV fans still waited and waited to not buy AMD. Why is that? 970/980 just launched and people are declaring the end of AMD unless they respond with an architecture of similar perf/watt in the next 6 months. AMD and NV have traded blows with NV having very poor architectures with GeForce 5 and 7 and AMD flopping with HD2000/3000 series. I wouldn't discount AMD just yet even though I think NV will win this next generation but AMD should be able to beat a 980 even if GM210 beats their 390X card.
