Yes, totally normal. At low RPMs, the oil pump does not spin fast enough to maintain a high oil pressure. At higher RPMs, the oil pressure is regulated by the regulator and it should be pretty steady...
Questions like this are why car manufacturers are no longer installing real gauges...

I just got my Oil Pressure gauge replaced with one that actually works. The gauge sits at a decent amount of psi during idle. Once i begin to drive it fluctuates (as discussed) but it goes above 60 and near to the point of 100? This is usually between 3000+ RPM.
As i drive on the freeway going at about 70-80mph at 3000-3400 RPM (if not more) its at that high psi amount too. Is there anything i should be concerned if not looking into?

People put too much thought into oil pressure. It varys widely based on the thickness of oil you run, temperature, etc.
Do you have oil pressure? If the answer is yes, then you're fine. You should see above 50 PSI at 3K. More if the regulator has been modified.
If you are crazy like me and have the Weber jet eccentric shaft mod, then 25-30 PSI on light oil (10W30) at 3K is normal, less then 10 PSI at idle and then normal pressure at high RPMs...Running a thicker oil is a must.

The Weber mod is really for high RPM engines as it greatly increases the cooling oil spray to the inside of the rotors. I did it on my engine basically "just because".
