Opterons everytime.
Under certain circumstances HT can make the CPU *slower*, and at best onl=
y=20
adds around a 20% performance boost.
A dual core CPU *is* two CPUs, with single digit % performance drop over =
2=20
full CPUs.

Issues? Almost exactly nil.
AMD64 support is excellent, if a little smaller and perhaps the tiniest b=
it=20
behind, the x86 profile.
