If you are getting temps of 90C and higher, and leave the computer as such temps for hours, that CPU will almost certainly deteriorate as a result of such high temps burning the silicon. If you can keep your temps under 90C, you are in good shape, although most people, mostly enthusiasts or overclockers looking for attention/bragging rights will want temps as low as possible (which they'll do by buying expensive coolers). I like my temps under 70C because I believe OCing can damage the CPU and keeping the temps as low as possible only prolongs the CPU's life. It's like buying a car with a supercharger installed, you really don't need it to get to work everyday, but it's nice to have in working order.
I get that if your CPU was hours on end 80-90c. In all the games I play and video encoding I have never had my temps near what Prime95 does and honestly don't know any program I have that would ever put my CPU on full load for hours at a time near those temps. For the sake of argument if my CPU hit like 80-85c 5 % of the time I ever use my computer would that even be a concern?

Intel sets their Tcontrol point to 68C. That's the normal operating temp they aim for, not the max load temp.

The ppt I linked in the other post has a detailed explanation including graphs of how Intel decides what temp to regulate their CPU's to.

But yea, normal operating temps in the low 60's and max temps under stress testing in the 80's is fine.

The one exception I'd add is if you were building a dedicated folding rig. In that case you'd probably want to keep the max load temp to around the Tcontrol point of 68c since the CPU is under full load all the time.
