Hi skylimit
I can't find any problems with your arrangement. One point to make sure of.
If there are any applications that need to use either of the network cards, you might have to ensure that manually, so use specific routes. You might even want to setup some static routes on the pc based on source IP address, if and only if you need it.
Otherwise don't see any problem with the arrangement.
