Can anyone explain why I get these results in OrCAD?
You would normally expect the voltage at the transistor base to be close to 1.65V since the base current is usually a small fraction of the emitter current, and you can see by inspection that the emitter current is in the 1mA range, and that the base divider operates at a similar current level (same order of magnitude at least) and gain is normally in the hundreds. 

However, because the transistors are saturated  (Vce is only about 50mV) the base current is much higher than you would otherwise expect. The transistors cannot provide decent current gain if you don't give them enough collector voltage to work.  

If you reduce the collector load resistors so that the transistors are no longer saturated you should see that the base voltage increases to much closer to your 1.65V calculation. Imagine if you removed R1/R2 entirely- the transistors would each behave as a diode from the base through 6K\$\Omega\$ to -3.3V.
