After much research and discussion, I think I found what i need. This will be used for Gb/s, OpenVPN, AES-256-CBC vpn it will be running. This looks like the cheapest thing I can find so far for making a Pfsense router out of. Do you see any potential problems with using this?
OpenVPN AES-256 and this symmetric would not be really able to imagine or expecting, only my mind.
