huh, because previously I had a Q6600 and I was able to change the voltages pretty easily without really increasing the temps drastically. Is the i-series different in some manner that makes even slightly adjusting their stock voltages a bad idea?
No it is just Ivy Bridge. You can get to 5.0ghz fairly easily and safely with Sandy Bridge but Ivy Bridge you cannot because the temps increase drastically when you up the voltage.
