I would. That's just me though, but anytime I do something on that level, I always format. (as long as it's an option w/o you having the fear of losing anything important)

Some people will say to reinstall but you don't have to. I changed my e6700 es to an e6850 and when I checked in the control panel>system It changed to e6850. But if it still see your old cpu just go to system and under cpu uninstall the old cpu and reboot.

Hello friend,

You shouldn't have to reinstall windows. The CPU should do the same, but if your upgrading there's a possibility you could get a error with the BIOS. If nothing has came up yet on the startup of your computer then you should be set

for the sake of preventing any bsod,corruptions and future problems yes a reinstall would be good. unless ur good and taking out pre existing drivers that's the only way it will come out smooth.

Pre-existing drivers for a processor ?

Drivers for a processor or hard drive are stored within the hardware. It's not even really a driver, to be honest I don't know what the name is. Thats why you can see the label and name of the processor/hard drive in the BIOS before windows even starts.

I don't see why Windows would keep them since you don't have to install any? Seems complicated ><!!

Clear CMOS and that's it. If you were to install a new motherboard then yes but not the CPU.

Awhile back a dropped a P4 into an old Celeron board, it booted right up, said windows was installing new hardware, rebooted, worked like a charm.

I replaced my core 2 e6300 with a core 2 q6700, without a re-install. Changing the cpu doesn't really change the OS in anyways since no drivers are required usually. Changing the motherboard is an entirely different story though.

The OS has the pre-existing drivers for hardware included. Just go to your device manager and right click properties to see the driver version and date (for example the CPU shows driver version 5.1.2600.0 for the XP machine I am typing this on). XP does not natively support dual core CPUs. Sometimes a reinstall is needed, other times, the service pack will correct it. The best way to check is to run Task Manager and see if there are 2 graphs representing the cores under Performance.

The reason why the bios shows the hardware is because the hardware is coded with basic bios code.

Vista on the otherhand does support multi core CPUs natively, and almost never require a reinstallation of the OS. When I upgraded to a quad core from my E6600, Vista detected new hardware, updated the drivers and restarted.
