The E6300 is not quite the best overclocking chip out there, mainly due to the fact that it has a low multiplier, if you want an affordable Core 2 OC chip, the E4300 will be a better choice:
"Though it would have been much more fun to raise the FSB to 533 MHz, we were unable to get that far. Remember, we have not raise any voltage for any of the components and we're still using the processor's stock air cooling. Running at 533 MHz FSB means we have to compare results at 3.2 GHz, either by using 6 x 533 MHz or 7 x 457 MHz, but 3.2 GHz is not really attainable using stock air cooling. At 466 MHz, the Intel P965 chipset on our Gigabyte P965-DS3P sample was already running quite hot, it was not entirely rock stable without a much more effective cooling solution. At that setting we were unable to run stable long enough to conduct our game benchmarks.
