I think AMD even had a card that pulled more from both the PCIe bus AND the power connectors than they were rated for... Was it the 6990 or 7990? Or am I wrong altogether... Oh well putting kid down for his nap so I will try to look up after. Any1 else wanna chime in on this?

already did. but to add to that and your's; there was talk of upping the power spec to 150 watts per slot in PCI-E 2.0 but i believe it died out with PSU manufactures and wanting to be concerned with the additional 150 watts+ on multi slot MBs. also there are power boards sold by the likes like evga to add more 12v to the pci-e slots to relieve the 12v from the 24 pin header not to mention MBs with additional power plugs.

That is going to be the norm for the 980. Who in his right mind will buy a 400$ card from previous gen when the 1070 is out at the same price?
The 980s are going to crash in price. Especially with the 1060 coming in a few months at most. Everyone will want to clear stocks, and that is what is going to happen.

that if you play some of the games which dont scale CF and bring the scaling down

If I remember correctly the press conference slides showed efficiency increase of 1.8x with special cases being up to 2.8x (most likely DX12/VR scenarios). If they we're comparing the card to Hawaii the efficiency increase is roughly 1.77x for DX11 performance, slightly higher in DX12. tpi is correct.

Only real knocks for this card is the lower than expected power efficiency. Other than that it does what it needs to do; it updates options for those who have around $250 to spend and it exploits a performance tier that NVIDIA has yet to cover with Pascal.

Also, I would expect the performance of the RX 480 to improve a lot as AMD takes a long time to get full performance out of their architectures.

why do you care so much about that 980 price dropping lower than ur pants?

so you cant play a bunch of games if you go CF ?

I am worried about Vega now. This 14/16 nm shift for both side has been super disappointing. Almost like they are holding back knowing they will be in this node for eternity.

PCIE 3.0 is still rated at 75W just like the PCIE 2.0, mainly because it is also backwards compatible so you can not mess with the connections too much.
Yes some add a bit more juice to it, or more correctly, they add more connectors in order to put less strain on the ATX connection and allow a draw from another source in order to give the CPU more stable power as well and not burn out the main power connector, and more than a few power suppliers also allow more draw from the 6pin.

Overall the 155-160w power consumption at max can be explained from other sources of power usage which are running, and they are not "cut down" from the equation for various reasons.

Its a new manufacturing process and neither company wants to pull a Fermi. Its completely reasonable for them to be this conservative.
