hey..
i am thinking about upgrading my 450Mhz pentium III to a 1000Mhz Pentium III.

Motherboard : Iwill's Vd133 (via's apollo pro 133 chipset)

i checked with the board manufacture and according to them, my version of the board supports these processors.(there was a voltage problem with earlier versions of my board)

the question is , will i have to reinstall windows ?............or will it recognize the new processor and updae itself ??
