Yes, you can upgrade it directly to version 8.3, however, please be advised of the memory requirement and also the complete change of the NAT feature if you are not aware of it yet.
Here is the release notes for your reference:
8.3: http://www.cisco.com/en/US/docs/security/asa/asa83/release/notes/asarn83.html
8.4: http://www.cisco.com/en/US/docs/security/asa/asa84/release/notes/asarn84.html
