My MythTV system now is a dual core AMD Opteron 170, 1Gb RAM, a 3ware
PCI controller (4x320Gb EIDE in RAID 5), Asus A8N32 motherboard (nForce
4) and a nVidia 7300GT PCI-E video card running Fedora Core 6. I have
two STBs and use the on-board firewire for capture. There is a PVR-350
in there that I use for surveillance cameras. I have plenty of CPU to
handle transcoding multiple shows, recording two shows and watching HDTV
on my 720p LCD screen at the same time.
I also use this system as an Internet gateway (Firewall, DNS, NTP, DHCP
e.t.c.), public web/mail server, MySQL, file server (NFS/SMB) and
wireless access point for about 4-6 other computers in the house. The
public facing services introduce low overhead as it's sitting on a cable
modem connection. (not much upload bandwidth)
The Opteron 170 is a socket 939 CPU and I paid $110 for it with another
$60 for the motherboard. $50 or so for memory. I also have a dual core
185 but it gets very hot and doesn't *seem* much faster although it
costs twice as much.
An E6600 would do it *very* easily. It seems the motherboard and memory
prices for the Core Duo systems are far more expensive than the AMD
systems. (the last time I checked) As it was mentioned before, an AMD
3800 X2 can handle HDTV, why overspend?
