New PSU, but system overclocked, should I set bios to default?

[Xyos]

I bought a new PSU in preparation for the new GTX 480. My system is overclocked (Q9550 at 3.7 ghz, voltage adjusted slightly). Should I set the bios to default before switching power supplies, or will it not matter?

Thank you in advance

If the power capacity of the PSU is adequate, there's no need to go back to the stock settings.
