This is exactly what we'll look at today. And with much of these articles I'd like to present the article to you as a DIY (Do It Yourself) experience, because the few of you who will go for Quad SLI, will be building that system yourself.
What do you need for Quad-SLI ? A pretty beefy system, that's for sure, here are your ingredients:
Not one but two times a GeForce 9800 GX2
nForce 680/780/790 mainboard
2 GB memory
Core to duo/quad processor - 2.67 GHz or faster.
Windows Vista fully patched and updated (SP1 recommended)
Quality 850 Watts or higher specced power supply
High resolution monitor (1920x1200 or above)
Positive thinking and a bit of luck

Nvidia GeForce 9800 GTX 512MB graphics card
Ever since the launch of the GeForce 8800 GTX in November 2006, the discrete graphics card market—at least at the high-end—has been a one-sided affair, with Nvidia dominating proceedings.
And with that, things haven’t really progressed an awful lot – we had the GeForce 8800 Ultra come to market almost eleven months ago just a few short weeks before the launch of the ill-fated Radeon HD 2900 XT. This was nothing more than a speed-bumped GeForce 8800 GTX with a nice new cooling solution that Nvidia wanted consumers to pay over-the-odds for.
The ATI Radeon HD 3870 X2 was AMD’s next attempt to create some noise at the high-end and while it did a reasonable job, it didn’t really rumble as loudly as the troubled platform maker would have hoped. While it did win some battles, it didn’t win the war in our eyes and since last year’s saga surrounding GeForce 7950 GX2 driver support, we paid particular attention to the 3870 X2’s drivers.
In terms of clock speeds, the reference GeForce 9800 GTX comes with a 675MHz core clock, a 1,688MHz shader clock and, while the memory frequency is set to 1,100MHz (2,200MHz effective). This gives some reasonably good theoretical throughput – doing the calculations gives around 432 GigaFLOPS of compute power, 43.2 GigaTexels per second of bilinear texture filtering throughput, a fill rate of 10,800 Megapixels per second and 70.4GB per second of memory bandwidth.
the GeForce 9800 GTX’s shader throughput has only been increased by 25 percent over the 8800 GTX. This is a little disappointing, as we’re used to some pretty big performance jumps generation-upon-generation, but this one is a little disappointing—especially considering the memory bandwidth and size reduction. Sure, texture throughput has been increased massively, but it’s only around four percent faster than the GeForce 8800 GTS 512 in that respect.
