This is a 4 core cpu. I am using a ASRock ITX motherboard with 16GB of
memory that is intended to be used for gaming. I am running -current
and so far the only real problem is that the AHCI controller suffers
from the "reset problem", see kern/53672 among others. I simply avoid
that issue by patching the source to use the "do not reset" quirk.
