So if all the work is done in the CPU, would a mother board such as the
"Asus M2A-VM HDMI Motherboard" with an ATI embedded video controller do
the job or is it still better to spend another $40 or so and use an nvidia
based board such as the "Asus M3A78-EMH HDMI Motherboard".

In either case, what would be the minimum spec CPU required (assuming
these m/b will support the required speed that is!!) to handle both TV1
and TV3 HD?
