htpc to nas. i run 4% on all 4 cores and 4-8% on the geforce 220 with a 25megabit/sec rip of avatar (i hate discs kids scratch them). so when they have those 1TB blu-ray discs i'll be godo to go. you'll be buying a 2nd wd live plus V2 or V3 to handle the newer higher rate media.
Look at google tv. a htpc - but lame. but it costs more than a craigslist refurb special or ebay asus essentio special. and everyone's banning those devices. htpc is good to go.
