![]() Heres the differences of 4870 > 4890, seems everything from the chip, to card, to heatsink were changed. http://www.techpowerup.com/forums/sh....php?p=1299332

![]() From the sounds of it the clock boost with T2 is going to be a bit larger than 4870 to 4890 and unlike 4890 won't come at the expense of more power consumption. If they can do that without extra transistors, power, heat, and noise then that sounds like a good thing to me. |

![]() Yeh sounds great to me too, but I think much like the 2700k which replaced the 2600k, only a small premium should be added on top. 2700k launch price was only $14 more than 2600k, and I would expect a similar % for this new card too. Looking foward to how well they oc, I'm guessing a good 50-100mhz average higher than current 7970.

![]() LOL....but how is it possible to have buyer's remorse for a card you didn't buy?What's the deal with that? I hope to upgrade my system in a few months.The only candidates are 7970/50 OR 470/480.A processor/MB upgrade/SSD is on the cards but I will swap out the aging 5850 first. Sounds like there are some good deals at around 400 bucks on amazon.com. |

![]() @demo - it was a joke, unwad panties, relax, crack open a cold one ![]() ![]() and you're right about the 4870 to 4890, that was a respin - plenty of changes. the info so far about Tahiti is it's a binning change. |

![]() So all this means is that AMD is going to take more of the higher binned chips. What happens to the lower bins that don't reach the Ghz edition? |

![]() Should we expect 7950s running even lower voltage with higher clocks? |

![]() Useless edition imo. Unless there is a voltage decrease and significant clocking gains (e.g., above 1200 MHz), will not upgrade. |

![]() Bridge chip on the 7990? I assume its the same PLX chip as used on z77 boards and GTX690, because I dont know of any others that support pcie 3.0.

![]() The PLX chip on the 6990 had 48 lanes multiplexed between the two gpu's and the peg slot. so each gpu could have 16 lanes to talk to the rest of the system or 32 to talk to each other. |

![]() I don't think it's likely that AMD would release a dual GPU card that was a near miss to the target - highest performance graphics card. with the 7970 v1 and 680 so close it's only going to take a little bump in speed to get it over the hump, which if you then stuck on a stick you can beat the 690. |

![]() Yeh imo 7990 should slightly outperform GTX690.
