Which is good, you shouldn't be running things at near their limits for extended periods of time.

But are those artifacts at a reasonable temperature?

Nvidia had actually imposed a power limiter to detect when a program like Furmark was being used and keep power usage and heat down. That was for the gtx 580 I'm not sure if current cards still do.

It's still the same. At the driver level, if FurMark is detected then the card will be throttled.

For this reason, it's useless for stress testing Nvidia cards. I'm not sure about AMD cards.

it seems like its the same thing, (stress test and benchmarking)

They can be used for the same purpose, yes.

3Dmark is more realistic to a gamers general and daily load, maybe a little harder.

Furmark used to be a good method for testing GPU's but there was a short falling out as the application began to fail to produce proper results when other forms of stress would do the opposite of furmark.

For example: I have a 290x.

If I furmark it will artifact and crash around 1070MHz

If I 3Dmark I start for crashing to desktop around 1170. - There is NOTHING ELSE other than furmark that causes me to have issues with this card like this.

this could also be the other way around, and also true with things like folding, mining etc.

It just doesn't happen to be a viable testing solution to some anymore.

I actually found just the opposite with furmark in the past, furmark being artifact free & stable at clocks that absolutely nothing had any stability in, like 750mhz was 24/7 stable for folding & gaming, up to 850mhz for benching, & no artifacts in furmark way past that. Furmark stable meant any other app would crash in less than 5 seconds under load.
It may have improved since then, I gave up on it a few years ago.

It was the other way around on my 680 too just as you explained, So I believe you 100%

My advice is to only use Furmark to test the cooling efficiency and capabilities of your graphics card. With it basically being a power virus, it will put the highest load on your gpu and vrms than any other benchmark program and game out there. It separates the boys from the men when it comes to testing the thermal capacity on graphics cards' coolers, and it's useful for troubleshooting temperature-related problems, like higher than usual VRM temps (which could be because of poor heatsink and thermal tape/pad contact, dust buildup, etc.). While some other programs can do that, Furmark does it better. It's kind of like the difference between 30 vs. 35fps and 100 vs. 130fps when comparing a 290x and a 780Ti (respectively devil-smiley-019.gif ). The 30fps difference will get your interest much faster than a 5fps difference would.
