I can understand that it's hard to believe until you actually own an E-350 APU. On a fresh install with all the latest drivers, Netflix will still lag every so often when playing HD content.
edit: I Google'd "E-350 Netflix." Here is the link:
I see there are known problems with Netflix and this CPU. It is a flaw in the Netflix client however. I can assure you, if the 700mhz ARM based Raspberry Pi can handle it, this CPU can. The E-350 has better benchmarks than some older Core 2 Duo's [cpubenchmark.net]
Netflix needs to figure this one out... But I am glad you pointed this out. That kills my hopes of an HTPC based on this... Now I am thinking about building an x86 router with this instead... If only I could find a case <$20
