32 vs 64 bits does not give you any raw performance boost for most

yes it will. FreeBSD/amd64 works at least 10% faster than
FreeBSD/i386 on athlon64 machine, when i386 version were recompiled
for P4. With default FreeBSD/i386 - it will be at least 30%.
just because it's not just 64-bit addresses, but twice the registers
(r8-r15) allowing C compiler to generate more efficient code.
For now AMD64 is the fastest and cheapest architecture - at least
with AMD processors, not intel clones. (YES now intel makes clones of
AMD processors)
I stand corrected ;-)...This is good info, thanks.
However, to the original post, you will not see 10-30 % performance
difference on your email or file sharing between an Intel Celeron and
AMD Opteron. These types of apps are Disk and Network IO bound.
Spend your money on redundancy/fail-over of hard drive and power
supply. Also choosing a well regarded NIC is important.
