Here is a screen shot of an 11 min 4k render in Adobe with my machine.
Again, I have the Intel Extreme 990x 6 core with HT tech., dual 1 gig video cards, ssd's, and other things as well.
To me this is not acceptable. I do not like when my CPU's are pegged out for 13 hours at a time, I don't know about you guys but I care about CPU longevity. I didn't spend $5000 just to run my pc with the petal to the metal all the time. I am building a new rig that will sustain my high end imaging for years to come.
provided you aren't increasing the voltage to the core while overclocking your CPU can run at 100% 365-24/7 and will be obsolete before you burn it out. Electronics do not degrade faster because they work harder, unlike mechanical devices like automobile engines.
