well 2 6970 are about $640 so add $240 for blocks and you get $880. That will be a little more than 1 6990 with 1 block (probably around $820 total). However, the 6970s will outperform a single 6990 by a reasonable amount. Also, as far as I know there are not any 6990 blocks out on the market yet.

ask yourself what do u really want?..a single card solution or a dual card solution.If u take a 6990 u will have better room for upgrades...like taking a 6990 now and later add on a 6970 or a 6950...or doing a quadfire and it will allow better breathing room in ur case...

now performance wise 2 6970 is slightly faster than a 6990 BUT u can easily close that gap and even take it further by slight OCs.....well many users in here have ordered their cards but haven't yet got their hands on it so only they can say what they have achieved with their 6990....

price wise 2 6970 costs either same as a 6990 or 20-30$ less than a 6990 depends from where u buy....i would like to go for a 6990(a bit of e-peen )

so at the end of the day it all depends on u....

Its nice to have just one card in your system but beyond that the Crossfire 6970 setup is the way to go. Cheaper, stock performance is essentially the same despite what some people say, but overclocking headroom is higher on the single gpu cards and cooling is better.

6990 is at 1-2% of 2X6970. AMD did better internal optimisations this time. It's not the 5970 anymore. People need to adjust to that new reality. Poeple are stuck in the past.

Go 6990. You can buy and unlock a 6950 later down the road and go Tri-Fire if you want to. More options if you need them later. 6990+ unlock 6950 will spank even 580 SLI for the same price.

be cautious of trying the unlock approach, as that is with version 1 cards, and chances are getting better and better that you wont get a V1, since they fixed that in the new version.

I'm not trying to unlock, I already have a 6970 and got my 6990 today to go Tri-Fire.

But finding a 6950 and unlocking it is a nice option for those who would want to go Tri-Fire later down the road.

Crossfire 6950s are the best option.. Even if you don't get ones that can unlock to 6970s, you're still looking at performance rivaling the 6990 for far cheaper.. That, and crossfire setups on water look awesome.

By time you need to upgrade crossfire 6950s, there will likely be better hardware around for similar pricing. If developers start releasing games increasingly more demanding than Crysis and Metro every 5 months, then you might have to upgrade to max eye candy, but that's not gonna happen.
