ESXi 5.0 reinstall with CPU change?

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.
