I'm considering getting a small-footprint "nettop" computer to use as a home theater PC with my Samsung LN40A550 HDTV. I've been looking at systems like the AS Rock ION HT330, the Acer AspireRevo 3610, or the Asus EeeBox PC EB1501. These are all systems with NVIDIA ION chipset (Intel Atom N330 dual core CPU + NVIDIA GeForce 9400 GPU).
Is the NVIDIA ION chipset powerful enough to support media streaming at HD resolutions (e.g. via Boxee, Hulu, Netflix) and casual gaming (e.g. World of Warcraft, Madden NFL) reasonably well without herky-jerky video output?
