Good. Better to buy when not in a hurry or under pressure.

Be aware that eco friendly is probably not audio friendly. I can get 16/2 
performance on my board and even though I don't use it very often, it does 
tell me that things are more stable even at higher latencies (and higher 
CPU loads). I did try to pick my CPU/MB for lowest possible latency, even 
to the point of getting ps/2 for mouse and kb (though I have had two extra 
kb plugged into USB with no problems). It is unfortunate that almost all 
MB come with built in audio when that is the first thing that gets turned 
off, but many server boards do not support video and cost more too. So a 
turned off audio set ends up being cheaper.

I did look at Xeon CPUs when I was looking for HW, They do offer some 
without the extra HT (AMD uses HT to mean something different) and more 
than 4 cores, but I don't know if the added cost of video (and the chip/MB 
itself) are worth while.

I would stay away from the "mobile" lines in Intel unless you really want 
an i3. (the mobile i5 and i7 are both dual core, slow CPUs) The only 
upside I could see to the mobile cpus was the included high res video. I 
am guessing Intel expects desktop users to use a card for such things.

The big thing I have learned is that any one cpu "chip" can only get rid 
of so much heat. So more cores means less speed (even virtual cores as 
with HT). Even graphics on the chip reduces performance in other areas.
