The 174.51 drivers resolve some stability issues. There is a multi GPU check box in the nVidia control panel so it doesn't work as a dual card out-of-the-box so to speak.
And yes, it is beaten by GTS 512 SLi, GTX SLi, 9600GT SLi and 8800 SLi (largely because it uses an 8xPCI-E bus internally) but slightly better than 3870x2.
I haven't tested it on an non nVidia board but I am guessing that if they make the (currently non GX2 exclusive) drivers SLi capable then there is a good chance that this can easily hacked to allow SLi support for non GX2 cards.

Qual HD3870 X2 qual quê ?!?
9800GX2 =
ya, no crysis, passar de 0x para 4x aa, provoca um drop imenso nos frames, sendo assim "papada" pela 3870X2...
weird!

Para quê? para jogar Crysis a 10fps?
Será assim tão difícil lançarem uma topo de gama que consiga correr este jogo decentemente a 1920X1200 com AA? geezz...tá a demorar...
e será que é dificil lançarem jogos de jeito bem optimizados ??

Não devemos estar a ver a mesma review...
Tou a falar da review Tweaktown que testa Vista, XP e AA/AF.
Claramente os drivers da 9800GX2 estão muito maus (espero eu), pq quer pelo preço quer por possuir 2x 8800GTS underclcoked a performance não ta la.
There has to be a new driver coming out soon. Websites have posted a newer driver than the one we received on the driver CD, but it doesn’t actually work. It refuses to install even though the driver is stated to be for the GX2.
If you had been reading the reviews online and thought “Bugger this, I’m off to get a HD 3870 X2”, we would hold off, at least for a week or two.
As soon as word of a new driver comes out, we will be placing the card back on the test bench to hopefully get the gains that we expected.
I have to say that until we got to our Windows XP tests, the 9800GX2 has been a complete let down. Under UT3 it actually looks like we have a CPU bottleneck with performance pretty much the same across all resolutions.
It out-performs the HD 3870 X2 in 3DMark06 under XP, along with it also out-performing the AMD counterpart in Half Life 2: Episode Two; a game that has always favored the AMD offerings.
At the moment the card doesn’t deserve to carry a new generation naming scheme, but with a little bit of hope seen from under Windows XP we could be alright. Now we just have to wait and see if we get a new driver in the next day or two.
Compatibility Issue:
*On Gigabyte X48, the R680 had no problem running through all tests. But the 9800 GX2 could only pass 3DMark06 on the very same board. Running any other games would results in errors, or worse, BSoD. Since we know from the previous test that SLI needs to be enabled for maximum performance, yet Intel chipset based boards do not support SLI, we might be looking at a compatibility issue here.*
