You probably don't need to follow every move, but it might make sense to
do some actual research if performance matters to you? You don't even
say what your performance critical server is going to be doing ;)
Core 2 generally performs well, but K8's are still pretty good with many
workloads thanks to their far superior interconnects. Most numbers I've
seen have been more based on games and media encoding in single socket
configurations, and in 32bit mode at that; not exactly interesting use
cases for most servers. Things get even less clear cut when you start
worrying about power consumption.
One of our more CPU heavy server uses actually depends very heavily on
memory bandwidth, which Intel are still lagging behind on quite
significantly, and of course things like lights out management and
driver support are generally far more critical than a 10% performance
difference in $random_microbenchmark.
