Four 6-pin – that’s what VR-Zone reports. But it’s hard to understand why would they chose such configuration, while 4x6pin connectors have the same wattage as two 8pin’s. My power supply for example has only 4x 6+2pins, so I wouldn’t be able to use two HD7990 without proper adapters. Long story short — it’s highly doubtful and stupid idea.

anybody want to play devil’s advocate on this one and try to think of technical reasons why 4 6-pin’s could be justified?

AMD, give us 7790 or 7830! My 460w PSU won’t handle 560ti :{
So i believe you will save me from gtx560

I am running HD7970 overclocked with an overclocked i5 on a 500W. You just need a quality PSU and check 12V rail amps.

I am hearing GTX660 ~ GTX580 and GTX660Ti 10-15% slower than the GTX670. That would put GTX660Ti at roughly the same speed as a stock HD7950. The thing is HD7950 has 3GB of VRAM as a “bonus” vs. rumored 1.5V for the 660Ti and cards such as MSI TwinFrozr III 7950 or Sapphire dual-fan 7950 overclock like champs (1.1ghz+). Unless 660Ti can overclock as well as the 7950, I think the 7950 is the indisputable price/performance leave for a gaming card at 1080P right now. The fact that it can be used for bitcoin mining on the side is also a nice bonus.

The pricing of 7950 is so ridiculous now, that you can pick up almost 2 of them for barely $100 more than a GTX680. Since at 1.1ghz it will be as fast or faster as a GTX680, that’s a heck of a deal!

At only 1025mhz, the 7950 is already nipping on the heels of the 680:

I don´t believe that GTX660 is on pair with GTX580, but with GTX570, and GTX660Ti about same performance as 580 or a little bit higher, of course with much lower power comsuption.Yes the 1.5Vram is short for 660TI, should be 2gb, 256-bit and 192*6(SMX´s)=1152Cuda Cores, that would be a better card that can be on pair with 7950 stock.
192-bit will be a bottleneck with AA filters on 1080p with new games and even BF3 or Crysis2.

Ya, there have to be. GTX660 and GTX660 Ti. NV needs to close the $200-350 price bracket. 1 card won’t do it. They need a card in the $199-249 area and in the $250-329 area.
