While Vue is running, without doing any rendering at all, how much influence does the GPU have versus the CPU? How much is the GPU used while rendering versus the CPU? I'm guessing the GPU is a big factor in running Vue since after installing a better one last year I noticed a big performance increase (like, Vue seemed like it didn't need as much time to think about doing something as it did before the new, better card was installed). Memory isn't an issue (32 Gb on the main board).

Any info would be great, thanks!

Last I checked, the GPU gets used only if toggled on in Vue's render options. And then only if there's an object in your scene that can benefit from GPU maths.

Reason I asked is that I’m rendering a scene with clouds and lots of blurred reflections and different brightness/shininess/anisotropic values (bare metal on an airplane) and all eight cores of the CPU are running at full chat. I leave it rendering and go to work, but upon return the PC has rebooted. After taking a look under the hood I think my culprit is going to be my eight year old (!) 750 watt EVGA PSU. Replacing that with a 1000 watt unit tomorrow morning since I think it was hitting it’s overheat limiter and causing a reboot because it was overtasked. We’ll see if it works...

Ok. I don't over-clock my stuff. So don't have experience about such things. On my system, 3D-Coat will make my video card's fan come on (could be the Cuda thing). But Vue doesn't make my video card sweat at all.

Not any of my business really, but as a hardware junkie, I'd say that 750 watt PSU is way too little for rendering with 32 GB of RAM. By the way, modern video cards will consume well more than half of your power wattage - they are the biggest drain on the PSU.

I have a 750 watt power supply for my ASUS/Corsair i7 32GB RAM system I been using for 5 years. Never any problems.

500 watts.... rendering for over 5 years on an 8 core i7 without a problem... but I've carefully chosen a GTX 750Ti that's moderate on energy consumption, yet is good enough for me.

Five years on 500 watts!!!!!!! Holy cow! You are to be admired!

The i7 3770 is quite energy efficient and still fast enough, even after all these years Vue rendering kicks into turbo mode 3.7Ghz is nice.

A few weeks back I bought a refurbished Dell workstation. Not for Vue, but for digital painting. It runs Vue and Poser well. The i7 is on par with my desktop and it has an Nvidia Quadro. 32Gb's of Ram and SSD. My desktop is maxed at 16Gb and has no SSD.

Best of all.... 200 watts only, yet the power of my desktop. My energy bill will be even less in the next 5 years
