Is NVIDIA's SLI technology something that works well with and is worth having with Lightwave?

SLI is only for games, and does not enhance 3D applications like Lightwave.

I thought they are putting two GPUs on a single card as well, and have also made their new GPUs so other programs can use them for computing, like 3D rendering. So if a program supports it shouldn't it be allowed to use a videocard for rendering power?

If so, it would mean at this point a workstation could use a dual quad core CPUs and an SLI set and have 8 CPU Cores and 4 GPUs in a single machine available for rendering.

First your confusing the issue, GPU rendering will become a reality for many things in time to come, it could be years before LW supports it.

Programs like Nvidia's Gelato do harness the power the GPU, but much more will be moved over the next few generations of GPU's. FFT etc, will be faster GPU's than the current CPU's can do.

SLI is designed for full screen OGL, it doesn't work in Windowed OGL applications like LW, Maya, XSI, Max, etc..... It was/is a game technology, so people can play Doom3 at 65fps instead of 35fps.

Nvidia want you to use Quadro cards for OGL and 3D applications, as they can make a lot more money.

QuadroSLI has produced no real benefits at this stage, because most applications are windowed and also bound by CPU restricitions, and not so much the videocard.
