Still, if you want my personal opinion, go for AMD. ;-) They are more

company that's _not_ in league with The Evil Empire. (Intel and
Microsoft are involved in the Trusted Computing Platform, a DRM-ridden
monstrosity that could end up being the PC that you simply can't install
anything other than Windows on...)

What year are you living in?

The future, apparently... <eg>

The Penryn Core2 processors consume much less energy then AMDs current
processors.

I've stopped monitoring Intel a while ago, but the Opterons in my new server
use 68 Watt each at maximum load.

In addition the Core2s are faster on a clock for clock basis and they are
available at higher clock speeds.

It's not just the processor that counts, it's the entire architecture. Even
though I'm not monitoring Intel's latest news anymore, I've read that
future Intel processors will use an on-chip memory controller like AMD has
been doing for ages now, which will then allow Intel-based systems to have
NUMA performance in SMP systems.

However - and I do know this much - the current batch of Intels still use a
single memory controller on the motherboard, which forms a bottleneck in
SMP systems and operates either at lower speed than the memory controller
of an AMD system, _or_ it performs at the same speed due to Intel's
radically high motherboard frequencies. And those high motherboard
frequencies _also_ raise the temperature inside your machine. Likewise the
FB-DIMMs that Intel appears to be using now, and they are _very_
powerhungry.

On top of that the Intel processors are much better overclockers.

That is something of which I have read that it has indeed changed, to
Intel's benefit. However, Opterons are highly overclockable. And another
however: don't overclock your system at all. But hey, it's _your_ money.
<grin>

Two years ago AMD was the better choice but not anymore.

AMD will *always* be the better choice, for those who look further than the
length of their nose. ;-)
