Your cpu is fine. Would like one clarification though, will get to
that in a sec... (Haven't read the whole thread)

Whoever said the 9746 driver was incompatible with a 5200 is a moron.
Okay, looked at the ubuntuforums thread. That's ancient. The 9000-
series drivers weren't even around yet (let alone the 8000-series). I
would pay no attention to that. 9746 is the one to use right now.

Nope, the generic driver is 'nv'.

Pretty sure this is the crux of your problem right here. Best as I
can tell, you have a straight PCI card (PCI-e cards show up
similarly, but mention pci-e link width, fairly sure AGP cards show
up as AGP). Is that indeed the case?
You *need* a PCI-express or AGP card for HDTV, the PCI bus will get
overwhelmed trying to move that much data.
