They tested all components for compatibility and found the resulting system to be remarkably quiet and power saving. I would like to build a MythTV box (combined BE/FE) based on these recommendations, as I trust in those guys and my own overview of current hardware is quite limited (though a built a couple of systems in the last 15 years). I just don't want to do any hardware experiments on my own and finally get a noisier system consuming 20 W more power than actually neccessary.

Therefore, I would like to temporarily use a separate PCIe graphics card and hope for the 780G drivers to get usable in the next months. At the moment, I just watch SD TV, so I don't need HDTV and BlueRay support yet (but the system should, in principle, be capable of this). My TV is a recent Panasonic LCD, so I want to connect the MythBox via HDMI or DVI-to-HDMI.

 I moved from a Phenom 9600/Gigabyte GA-MA78GM-S2H to a 4850e in an
ECS A780GM-A for the power savings of the cpu and the extra pci slot
of the mobo.
 The 780G/4850e combination is running on a 22" 1680x1050 screen.
 Bottom line, it [mostly] works great.  The _only_ problem left is the
resolution issue (corruption on changing between channels of different

 On the flip side I have never had these issues with an nVidia card
and they have just released the VDPAU API which looks very promising.
I've seen passive half-height 8400GS for around AU$50 which may just
fit the bill[0].
