The original question is lost in the noise!
a) You really want lots more RAM
b) AMD X2 works well and has lots of technical pluses.
c) Can anybody declare that core duo intels work *marvelously*?
d) I see opterons hyped
e) I am mostly happy with my X2, comparing to my P4/3G, but (ABIT AN8 939) I'm
sometimes uummmish:
skype crackles terribly when doing disk io (WD raptor SATA) eg a backup (P4
did NOT)
Response is sometimes sluggish ie 1 cpu is tied up eg starting VMware-server
the other IS free but mouse movement is sticky
Burn a CD AND work the other CPU and Burn fails!
All of which point at IO, but my P4 competed very well in all the above.

Natch YMMV, and I've tried only two MBs an ASUS AN8 that kept freezing and now
the ABIT AN8. Upto 5 clients
