Nvidia GT200-successor on 22th October?

[Stevethegreat]

NVIDIA GTX 350
GT300 core
55nm technology
576mm
512bit
DDR5 2GB memory, doubled GTX280
480SP doubled GTX280
Grating operation units are 64 the same with GTX280
216G bandwidth
Default 830/2075/3360MHZ
Pixel filling 36.3G pixels/s
Texture filling 84.4Gpixels/s
Cannot support D10.1 .10.0/SM4.0[/i]

BTW if the above are the real specs of the supposed upcoming card from nVidia, then it would be about 3 times faster than GTX280 on real world performance, as long as it is not bottlenecked by the memory bandwidth (considering that 3360MHz of GDDR5 gives enough headroom, I doubt it would be the case). That would make this beast 2 times as fast as 4870x2 on REAL world performance !!!

That's exactly what makes me disbelieve the rumors, there was never such a jump in performance by either of the companies, even the 8800GTX was far less faster from 7950GX2 than GTX 350 is supposed to be from 4870x2. Technology moves fast, but not THAT fast, even with 55nm you would need a nuclear reactor to power that thing and dry ice to cool it...

Edit: Here's a GTX 350's specs' pic (doctored most probably)
