Those were the old leaks and nothing new there, thrown in with a bunch of other forum rumours (also removed). Notice OC3D originally posted the image for a couple of days before pulling it and confirmed it fake, months after several other sites did.
If a 6GB GM200 comes in at £650 tops for full core and 12GB GM200 is selling for £800, surely you'd pay an extra £150 right now? Albeit it's only useful for those with 3 screens or good old 1440 and right up to 2160 displays.
Understandable to think twice like I did when you look at SLI, personally wouldn't pay than £600 per card tops. Saying that through gritted teeth when highend GPUs used to cost £230 7 years ago

1/32 double precision means for work its asking a lot - even the Quadro M6000 is based on the same chip and lacks double precision.
