No, Quad SLI = 4 GPUs = 2 GTX 295s. Quad SLI is the maximum possible number of GPUs supported by SLI (4), and is only possible using 2 dual GPU cards. You can use 3 single GPU cards in Tri-SLI, however.
So you either meant two of these cards in SLI (i.e. quad SLI), or you are mistaken in thinking that you are actually able to use 4 of these cards in SLI (8 GPUs).
but that asus mars has 2 GTX285's in each card, and so put four of them together, 4x2=8 GPU's I know its 4 cards, but each one of those cards has 2 GPUs....
Actually that technically isn't possible. Electrically the bandwidth is only 16x, therefore the bandwidth required to run a total of 4 of these cards making 8 GPUs would need to be doubled. Meaning you would need four 32x electrical slots which if I'm correct that standard (PCIe 3.0) will not be released until late 2012 at best. By then we will have GPUs that will easily do what 8 of today's GPUs can do. Not to mention you would need at least 1800w of PSU with not less than 32A per 12V rail, making this type of system only feasible with a Dual Socket Lynnhaven setup requiring not less than 24GB of memory and an SSD that could push beyond the 6 GB/s barrier. I can only imagine that this would even require a subset of Memory addressing for I/O mapping at the electrical level even on a 64-bit OS such as Windows Vienna or even System 8.
The point is....don't get your panties in a wad just yet, this will come eventually but you will never probably never see a system with 4 of these running, let alone even just 2 of them.
That's not exactly accurate. Any game that supports SLI supports any number of GPUs that nVidia currently supports in SLI configuration.
The inaccuracy is that not all games support SLI. Most do, but there are some notable exceptions. And some games actually run *worse* with it enabled...a key example I can think of being Flight Sim X.
Now that we've thrown 'em off the trail, use the form below to get in touch with the people at Engadget. Please fill in all of the required fields because they're required.
These in Quad-SLI *faint*....
How many games utilize 4 GPUs right now?
Isn't it 8 GPU's?
And I meant at the price...
@ freddie
all the games, all the time

"How many games utilize 4 GPUs right now?"
That's not the point at all. This setup will make my wang HUGE.

I can dream....
