I wouldn't recommend Atom for heavy duty upsampling

Your point on IRQ is important and will have impact on SQ.

Atom processors + NM10 chipset has large appeal for audio due to low power consumption and display interface is from CPU. But it lacks SSE4.1 and 2MB L2 cache. There are other limitations like "in-order execution" making computationally intensive tasks less efficient. This suggests Atom based solutions are best for non-upsampling. This leaves upsampling to the DAC which is not ideal. Atom processors using 32nm + DDR3 technology may improve this situation.

Core i3 + H55 is superior when upsampling and power consumption comes very close. NM10 uses 2.5 watts vs H55's 3.5 watts. Only downside on Core i3 based solutions is the display interface which is from the chipset.
