it works but it is useless for most people, there is a small increase in 3dmark scores but not enough to warrent a 2nd card. Some applications are actually worse off when using quad sli where only a few benefit. So in efect it does work...just very badly.

There are other review around showing the same. Fear for some reason works really well ith quad sli while other games there is no increase and even decrease in performance.
Some say its the drivers, some say its not having a true 32x PCI-E motherboard but now there is with the new 680i motherboards so...

As above, it doesn't work.
I'm assuming like others have said - even with the official drivers - its probably broken... however I haven't seen anyone test it with a CPU that is fast enough to max out a 7950GX2 let alone 2 of them so they could have been seriously CPU limited...
i.e. in the link above they used a AMD Athlon64 4000+, in many of the tests I've seen the 3800+ used a X2 4600, etc. none of these are valid for testing with quad sli.
Something I did notice tho... someone had a couple of early sample cards that had 2 SLI bridges on it, using hacked drivers and showing some pretty nice performance gains - most of the other reviews I've seen the cards only have 1 SLI bridge capability - I don't know if that is part of the performance problem - maybe it can only handle the throughput of normal SLI with just 1 bridge.
Unfortunatly SLI doesn't work with my motherboard - although their are hacked drivers for SLI available for it - but they are quite old and afaik don't support quad SLI. Otherwise I'd give quad SLI a whirl if I Could find another card cheapish.

Trust me, people have tried over XS with 3ghz X2s and Conroes.
Even people with 2.5ghz X2s say nothing happens when Quad SLi is enabled, even at 1600x1200, 16xAA 32AF.
Sell them and get a 8800GTX.
Gonna need a conroe at 3.5gig or faster to even see a difference from 1 7950GX2 - I just don't believe that an X2 has the horse power to drive a quad sli setup even if it actually worked... which as I said I'm pretty sure it doesn't.
And no way am I selling my 7950GX2 - I get 200-300fps in pretty much every game out there at maxed settings - I simply don't need an 8800 atm and when I do there will prolly be newer cards...

What setting are you using, i got myself a GX2 and in games like FEAR,BF2 it runs like ****, eg in bf2 all setting high with 4x AA no AF its not to bad but as soon as i use AF framerate drops like mad 35/40 fps, and fear well its very bad
Quad SLI works a treat in OpenGL, but that's it.
As people here like to forget, the issue is DirectX9 not allowing more than two (three?) frames rendered in advance of what's put on a screen. Ergo, half of a quad SLI will be twiddling its thumbs.
OpenGL works fine, but there are only two current games that use it: Quake 4 and Fear.
If they're all you play, then great. It will be interesting to see what Windows Vista can do with twinned 7950GX2s... however, I'd suggest you sell one and pick up an 8800GTX with the money

I usually run 4x AA, 16x AF on Good Quality (I find High Quality eats FPS like mad for very little difference) FEAR runs pretty good generally 200-300fps indoors tho I have seen it drop to 70-80 outdoors.
Use something like nVTray to make sure its actually using multi-GPU mode - as I've found sometimes it will get stuck in single GPU mode quite often after playing with settings in the control panel - even if the control panel has multi-GPU selected.
My 7950GX2 overclocks very well tho - i.e. on stock clocks I was getting 120fps in FEAR in one scene - with a bit of overclocking it was doing 200, I also find it very CPU dependant in some games... lost coast stress test with my E6600 at stock speeds gets 150-160fps but when I clocked the CPU up +25% my fps avg. went upto 210.
