For $700, it can sit on a store shelf somewhere until hell freezes over, or I change my underwear, whichever comes first. :ROTF:

Or you could pre-order for the staggering price of €715 (that is ~1000USD)

yea but sometimes people prefer it.. i myself would prefer this to dual 6970's if i was still on water and was using my stacker..i just switched but before i would of definitely went this route being as they perform pretty much identical.
mainly for the reason of a single card looks cleaner imo and needs less cabling also keeping the interior cleaner while still maintaining the same performance..

of course price would have to cost a little less then 2x6970s

isnt it cheaper to buy 1 6990 waterblock than 2 6970 blocks?

Yup, perf diff will undoubtely increase as res. goes up but I'm eager to see how much. I'm building a SB rig for gaming so I'm limited at 2x8 pcie lanes with 2 cards CF/SLI and I'm very curious if this will be a bottleneck considering the firepower provided by 2x6870 at Eyefinity resolutions. Couldn't find a reliable article on this subject, though.

TPU did a quick review of pci lanes and perf loss, i think back with 5870s

Thanks for the tip. :up: I'll check it out.

HardOCP did a similar test too. IIRC the results were a bit contradicting against the TPU test. But I would not be surprised if 8x bottlenecks a 6990.

As for the loudness of the card coming, just look up the xfx 5970 limited edition review that uses basically the same cooler. It's loud as hell, though the temps stay decent. Now add 100 W more load to that and you have 6990. The temps will go through the roof regardless of the already insane fan speed. This card really will need water to be usable. I don't think even an accelero xtreme could keep the card cool properly.

With a ~700$ price tag it just makes no sense. Two unlocked 6950's is the way to go if you want performance at a decent price. Or 570 SLI if you want quieter cards.

Dual cards in CF/SLI would be 2x8 pcie on socket 1155. One 6990 or the rumored dual Fermi card would be at 16x pcie lanes. :up:

but still 8x per gpu.

they share the same bandwith on the pci express .... ( but maybe i miss something )

just that xfire 2 different cards = 8x per card
6990 on 1 16x is 2 gpus on 16x ..16/2 = theoretically 8x per gpu.

Im going to jump on the 2x 6950 boat and say that would be the best bet again for MOST people because. you get the same perf. You get quieter cards, all the ehat get dumped out the back of your case. You can use AIR cooling practically, it's cheaper and 2 cards just looks plain cool:up:

Nope. One card CF/SLI ala 6990 gets full 16 pcie lanes. There's no pcie splited lanes because there aren't two devices sharing the bus.

Time for you to update the first post, onetreehill.

Anyway, the card performance looks quite nice, though it does consume a lot of power, but that was expected due to reusing 40nm. Though GTX 580 SLI wins most of the time.

I never really expected it to be faster than 580 SLI, but at least it's practically 6970CF performance, which I am rather glad of.
