two 6970's would be like 670 or 680 so it makes sense.
no it doesn't makes sense because that right there is two full cards that are faster being cheaper than one. plus there are some models on newegg with rebates making 6970 crossfire for 640 bucks. that's 60 bucks cheaper for a faster, cooler and WAY WAY quieter solution. just look at the noise that a 6990 makes in the anandtech review especially when overclocked.

Yeah based on all the reviews/benches 6990 is not worth it whatsoever.

I highly doubt the 590 will be any better; maybe now AMD/nVidia will stop this nonsense and just get on with the new series of cards.

I found this to be very interesting!

Quote from Anandtech article............

". The switch on the 6990 is slightly recessed, not by enough to make it hard to hit but enough that you’ll never accidentally hit it. Flipping the switch would need to be a conscientious action, which makes sense given the fact that doing so would void the card’s warranty"

So if you hit the switch the warranty is void? Thats not good.

yeah I thought was quite odd.

And the pci-e spec does not mean crap.

Quote:

" So does PCIe compliance matter? For mainstream products PCIe compliance matters for the purposes of getting sales; for everything else including niche products like the 6990, PCIe compliance does not matter."

So all this 300 watt limit crap was just jibberish. So we will see 2 full gtx580's on the gtx590.

How many cases can fit 4?

about 12, last I looked, but they are exspensive.

My point was if you want to go quad-fire and you only have 2 PCIe x16 slots these are your options, if you arent going for the extreme this type of card isnt for you anyway, i dont see how a $60 premium ($120 for two) is a bad thing when you end up saving money on the case that would be needed to fit 4, the cooling, and the more expensive motherboard, plus a more expensive PSU (instead of 4x 2+6 pin pci power connectors you would need 4x 6 pin pci power and 4x 6+2 pin power) At the end of the day if you are going to extremes then this makes sense, and the $60 over a pair of 6970's is fine.

This card is so damn hot and loud, GTX 590 will have to come with a triple slot cooler in order to stay cool enough to function. What do you guys think?

I think they should just ship the suckers with a water block and call it a day.

From the Hard/ocp review.

Gtx580 sli vs the 6990..............

"In this comparison the configurations are worlds apart. The reason is the pricing, the GeForce GTX 580 right now is still around $500. Therefore, SLI is $1000. This is a whopping $300 more expensive than a single Radeon HD 6990. However, our evaluation has revealed that this extra $300 does give you a better gameplay experience in almost every situation. In every game we played the GeForce GTX 580 SLI did give us the highest framerates. Beyond that though, GTX 580 SLI provided the smoothest gameplay. There was less choppiness with SLI and it seemed lower framerates felt smoother on GTX 580 SLI than it did with 6990 or 6970 CFX. If you've got the cash to burn, you can't beat GTX 580 SLI for true multi-display gaming performance."

More AMD microstutter crap mabe? That would suck.
The phrase " it seemed lower framerates felt smoother on GTX 580 SLI than it did with 6990 or 6970 CFX" seems like bad news for this card.

Possibly but we have to keep in mind that GTX 580's have been out for 4 months or so and have had time for their drivers to mature. And the real point for Dual GPU cards is to be able to get as much performance on a SINGLE card as possible. TWO GTX 580's beat a SINGLE 6990, well we have always been paying a premium on single card solutions over dual, just like GTX 460's in SLI is cheaper then a single 580 but the 460's tie or beat out the 580 in a lot of games.

The GTX580 SLI setup in the HoCP review drew 200w more than the 6990. They will have to underclock/bin like mad.

As for the 6990, the card will only be good with watercooling. Otherwise you're better off with 2x6950 or 2xGTX570.

Probably premature drivers or something, in terms of micro-stutter all multi-GPU configs have this. Also the GTX 580 SLi is the fastest dual GPU solution so that helps it with it's "smoothness."

I would have expected power consumption to be a bit better, but given its performance there's nothing unusual about it as is.

It's pretty clear this generation could have really used a die shrink instead of being stuck on 40nm.

The GTX580 SLI setup in the HoCP review drew 200w more than the 6990. They will have to underclock/bin like mad.

As for the 6990, the card will only be good with watercooling. Otherwise you're better off with 2x6950 or 2xGTX570.

I think we can take a look at what AMD has done with Antilles and you can easily expect what Nvidia will have to do with the GTX 590. For Nvidia's dual GPU to be faster it's going to have to use more power. There doesn't seem to be any way around that. I suspect the 6990 and 590 are going to, for all intents and purposes, be extremely close in performance, because both cards are going to run into the limits of the available power. This race will probably be much closer than the 4870X2 and the GTX295. Even in that case the GTX295 had the luxury of using more power than the 4870X2, but with the 6990 getting closer to the limits that doesn't leave much headroom for the 590. The performance difference is going to come down to driver support on a per game basis. Bank on it!

Pretty crappy in x-fire with 2 6990's too. :(
Those AMD slides lie! :(

Heh, not much to see.

Loud & overpriced...they can fix the pricing, but the noise, i think non-reference cooling would be required for that fix.
