ESXi 5.0 reinstall with CPU change?

Hi,
this is simple question:
MUST or SHOULD I reinstall ESXi 5.0 host if I change and add CPU?

I have currently Xeon E5420 CPU (Quad-Core, 2.5GHz, 12 MB Cache).
I will install TWO Xeon L5420 CPUs, which differ on spec sheet only by power consumption; all other specifications are exactly the same. But notice, that I will install 2 CPUs, while now there's only one.

There is NO Requirement if you change the CPU or Add another CPU, ESXi will recognize the change and update its configuration automatically.

Simple answer is no..as @@hanccocka already mentions. Your host should recognize any hardware change upon boot up.
