So it doesn't matter how high i raise the voltage right, as long as the temps are okay?
well, yes, it does. If you put the voltage too high, there's a chance it could damage something. Even if the temperatures are fine.
I think my CPU can go further than 1.725V without overheating, but I am weary of pushing it even that far.
*edit*
Whenever I increase the core voltage past about 1.6V, I always increase the HTT CPU <-> SPP voltage, to prevent there from being too much voltage difference between the CPU and HTT bus
if there is too much difference in the voltages, I think it can damage the memory controller (which is on the CPU die, in AMD's case).

Swiftech MCP655
Swiftech Apogee GT with AM2 plate
Thermochill PA120.3 radiator, with 3 x 120mm fans (1200RPM)
AC Ryan 120.3 Rad Grill
Danger Den fillport
Clearflex tubing (1/2" ID)
probably spent over $500 AUD on it.
That's not including the case, which I picked and modded specifically
for the gear I have (and cost me about $350 AUD, plus about $50 for the perspex, and about $50 for the eight 120mm fans)
But IMO, the result is priceless.
And I can still use the case and water cooling kit for future hardware
