I think the first thing we can say is that it's nice to see that AMD got the Catalyst out on time this month and it did indeed come out during March unlike the Catalyst 12.2 which fell into March.
The second thing is that this is a weird driver release. The Catalyst 12.2 was labeled as 12.3 and it made us wonder a bit. Was AMD just throwing an earlier version of the 12.3 drivers out there to keep up with the monthly schedule? In the end we'll probably never know the truth.
