I'm currently using a Core i5-661 which is 2 cores+hyperthreading
integrated with graphics. It's worked pretty well most of the time but
I've found the graphics side to be temperamental probably due to the
Intel video driver. I can pretty easily make X completely crash
dropping back to my gdm login screen. I do not use this machine for
Myth so I cannot say anything about that but it runs NetFlix fine in
Windows native or in VMWare under Linux.
Still, I've been pretty impressed with the processing power and
strictly speaking this is a Linux issue because the machine is very
stable in Windows so I'm sure it will get worked out _someday_.
The machine has 3 hard drives and two monitors and only draws about
150W running KDE.
