3800+ and another CPU question

[karpfish24]

ok so ive heard that for the x2 3800+ you can get either a Manchester core or a Toledo core with half of the L2 CACHE disabled. Which of these is better for OC'ing? I have a Toledo. My other question is about getting a new CPU. If you were to get a new cpu would you need a new OS? Ive heard that Windows is registered through the serial for your processor. is this true and what would you need to do if you got another cpu?

The Opteron 165 is the best dual core to overclock.

You have to do a repair install with the windows installation cd.

The Toledo core is actually the Athlon 64 model, the Manchester core is the Athlon 64 x2 model.

The only time you need a new copy of an OS is when you buy a new motherboard, and hard drive too I believe (but most never get rid of hard drive's they simply add others.
