Quad sli doesn't work properly, so it won't tell you much. Crossfire is better because it actually works.

Yeah as said above, there is no Quad SLi as it doesn't work.
*Sigh*
It does work in some instances. The AFR implementation that SLi likes to use works extremely well by rendering four frames into the system buffer. However, DX9 only likes to play with three. The problem, as such, is that everything coded in DX9 (i.e. anything not based on OpenGL) will not perform as well as a high-powered, two GPU system (aka Crossfire X1950XT-X-Y-Z-111!!!one). OpenGL titles, however, will notice a much more significant performance boost.
Things will start to get interesting with the next generation of GPUs that are prepped for Vista. Assuming they don't require a powerstation to run, of course.
The bottom line is this:
Nvidia's architecture is not as straight-line powerful as ATi's, but it uses a helluva lot less juice for only a small, average forfeit of fps.

It doesn't work, simple, why do you think everyone raves about x1950 XTX Crossfire destroying Quad SLi, because the Crossfire works, the Quad doesn't, it isn't fair to put 2x working cards against 2x that don't work everyone knows that, and as Gibbo said, he doesn't know why Nvidia are marketing Quad and saying the GX2 can do Quad etc... as it doesn't work, the drivers for Quad were released ages ago, it still doesn't work.
If Quad SLi did work it would totally destroy the x1950 crossfire, then the boot would be on the other foot, and all the Nv ppl could be ******* their selves laughing, but it doesn't, its false advertising by Nvidia.

The why do the review sites I look at show otherwise?
I'm just curious as to why it doesn't work when reviews clearly show it making some difference?
Now, if you were saying it doesn't work properly all of the time and as such is an incomplete and half-baked product, then I would wholeheartedly agree with you. But you're not, so unfortunately I disagree.
And no, I don't own any Nvidia hardware, nor do I plan on buying any in the near future.

The end result being, when comparing a single 7950GX2 versus a single X1950XTX card, the GX2 is easily quicker.
When comparing 2x X1950XTX cards in crossfire versus 2x 7950GX2 cards in Quad SLI, the crossfire setup will outperform the Nvida cards.

Quad SLI is pretty brutal (when it works): http://www.firingsquad.com/hardware/ati_radeon_x1950xtx_crossfire_performance/page6.asp
x1950xtx-crossfire simply doesn't have the same raw grunt. If you look at the FEAR 1600x1200 results on the next page, it has a minimum FPS of 36, compared to Quad-SLI with 56. That's over 50% faster.

Hi there
X1950 XTX Crossfire is better for most users seeking that extra power and those who mainly play D3D games.
However if you do have a 30" panel and wish to play with AA and AF too maximum levels then Quad SLi will show its power and as already noted it works fine in OpenGL.
Just for most the X1950 XTX Crossfire solution provides better performance in most games and does cost less too.
It is possible though with the release of DX10 then a QUad Sli system will get a good performance boost making that setup more future proof. However this is me guessing.

I work on the premise that if the site that one wants to link to supplies ANY product that OcUK supplies then it is a no no.
I see no issue in linking to other forums belonging to sites that do not retail product, or linking to non-retail review sites for information.
I hope to be corrected and not punished if I am wrong.
