What will it do to the life expectancy of the motherboard, Asus P5B Deluxe or Gigabyte DS3? Is there a prefered way to overclock so as to maintain the lowest possible heat and damage?
That remains to be seen. Most of my motherboards have died within 3-4 years anyway... without overclocking. On the DS3, the Northbridge appears to be the most at-risk chip on the MB. At 430FSB, that thing gets HOT. I'm working on better Northbridge cooling.
