Architektóra dla Intel Core 2 Duo

Przeczytałem ostatnio coś takiego:

The Core2Duo is a processor that uses the IA-32 microarchitecture with
EM64T extension. That makes it similar to an AMD Athlon 64 processor.
Although it is not a true 64 bit processor (not IA-64 microarchitecture)
it can process the 64bit instruction set and features the 64bit address
register extensions and general purpose registers. That means you can
choose to run a traditional 32bit x86 or an x86-64 system. An x86-64
system is capable of running 32bit and 64bit applications. The 64bit
applications can use 4GB address space per process (2GB in x86).

Czy warto więc instalować x86_64? Zainstalowanie x86_64 daje jakiś
przyrost wydajności na tych procach? Czy może lepiej po prostu
zainstalować i686?
