As a reference point, I just built a new frontend for HD:
X2 3800 (65w) AM2
ASUS M2NBP-VM MB with integrated Nvidia 6100
1GB DDR2 (2x512) 800MHz
Connected via Gig E
nvidia driver 1.0.9746
It displays 720p/1080i HD content on a 1360 x 768 via VGA at 40-50%
CPU with de-interlace turned on, I forget which algorithm. Cool N
Quiet is enabled and the CPU stays relatively steady at 1.8GHz, when
watching SDTV it drops down to 1GHz and stays at 20-30%. I have
standard XVMC enabled.
Motherboard, memory and CPU cost about 320USD from newegg. I am very
happy with the performance. This replaced a celeron 1.4 with 512M of
PC133 + GF6200. Power consumption measured with a kill-a-watt, is
between 65W and high 90W @110V.
