Does running Prime95 at priority 8 or 9 make a difference?

When testing system stability, does running Prime95 at priority 9 instead of priority 8 really make a difference?

One thing I've noticed is that at priority 9 Prime95 sucks up so many CPU cycles that even the OS (Windows Vista in this case) has trouble functioning - connecting/disconnecting USB devices (mouse, keyboard) takes eternity, DWM occasionally crashes, and good luck if you forgot to disable the screen saver - you might not be able to get back to the app. My concern is that when these things happen, it's difficult to tell what's crashing due to Prime95 hogging up all the CPU cycles, as opposed to due to CPU overclocking. I'd much rather run Prime95 at priority 8, but at the same time I don't want to jeopardize the validity of the stability test.
 
Run OCCT. It will do the linpak stress to the cpu and the gpus at the same time. Works good for dialing in a gaming rig.

Yes, it gives not enough CPU time to essential OS services and can crash the OS.
Regarding stability testing, if you run something else 100% CPU at priority 8 or 9 then maybe this would be a valid test.
As that doesnt happen really, there is no point in testing high priorities.

In one word .. NO.

Running Prime 95 at normal priority or high priority is the same. It will still crash if you system is unstable. There are a lot many stability testing tools out there but i've been priming since my Celeron 300 and PIII 700 days and still trust P95.
 
I also say it doesn't matter what priority it's in. While I find P95 a great overnight burn-in test, I like using that IntelBurnTest - it seems to run the CPU hotter, but also allows you to find your max overclock quickly. I usually run the max of 20 runs, then if it's stable, keep turning up the clock/voltage. If it fails the test, then I bump it down and do an overnight of P95.

This combo helped me cut down on the time it takes for me to OC now, since i don't haev to wait overnight as much.
