I just overclocked my GPU and am looking to stress test it. I am planing on running with FurMark to stress test it. Overclocked it with MSI Afterburner.

Is there any other better stress test software or should i just go with FurMark? Also, how long should i let the stress test run?

One last important thing i need to know is, do i need to sit throughout the entire stress test or can i just leave it and do something else? (Do something outside of the PC.)

I am also using MSI AfterBurner.
The steps are like above, more or less.
There is some differences, I do it about +25MHz per step/bump on core frequency, the max desired temperature is 70'C (stop OC if the temp goes above 70'C) and I am using Witcher 3 as stress test (simply play the game).
ah...I have GTX970, as info.

MSI Afterburner is my favourite Overclocking program.
Overclocking tips :
- don't modify the core voltage
- don't touch the power limit
- add 50 MHz bumps on the Core Clock, after every bump run Furmark for 1 hour. (if you're getting artifacts, black screens , blue screens, 85+ degrees - LOWER YOUR FREQUENCY , until your GPU it's stable)
- add 50-100 MHz bumps on the Memory clock

Watch your temperatures with HWiNFO : http://www.hwinfo.com/download.php - when you're reaching 85+ you should stop Overclocking.

50 - 100 mhz bumps are pretty big, I agree with guanyu, both on core and memory, 25 mhz.

Also you absolutely should modify core voltage (if the card is unlocked and its available) and power limit. Once your clock speed increases become unstable, you can use both power limit and core voltage increases to make it stable and allow you to push it more. I have my power limit up 20% on my cards, my overclock would never be stable without it.

Saying not to do that is cutting off a huge chunk of your tools for overclocking!

As for not watching the tests, well the problem is if you aren't at least checking in on it every few minutes you won't know if its crashed, and you can't see any issues. I would say at least be in the room so you can pay attention to it. Also if its creating artifacts and things like that and you don't see them and stop the test that could damage your card.

Furmark creates way too much heat...don't use it. OCCT has a good GPU stress test. A couple of hours is plenty.

In regards to voltage and power limits...you're going to limit your overclocking potential a great deal, if you don't increase them. Especially with Maxwell GPUs....
