AFAIK yes, but
according to Anand if you want to do 480p Flash upscaled to fill your screen, you might run into serious problems, even with dual-core Atom D510.
The guys who responded to my
Atom spec thread suggested either a non-Atom machine, or else if I must go Atom then get one with ION, so that's what I did. 480p Flash is a piece of cake, upscaled to any reasonable resolution. I can even play Blu-ray on that thing flawlessly (dual-core Atom 330 with ION).
