I dunno, I actually find AMD's way of doing things more confusing. NVIDIA generally releases a beta or WHQL driver around the launch of a AAA title to ensure it runs decently on their cards.
AMD indicates they have a monthly release schedule, but this is how it really works (Nov and Dec of this year):
Cat 11.11 gets released
Cat 11.11a hotfix gets released
Cat 11.11b hotfix gets released
CAP (Catalyst Application Profile) gets released
Cat 11.11c hotfix gets released
Cat 11.12 gets released, but doesn't contain all the hotfixes applied to Cat 11.11, and AMD suggests that gamers should be using Cat 12.1 preview.

So which is easier, looking for the newest WHQL/beta driver from GeForce.com or grabbing the newest driver that doesn't actually contain the latest hotfixes and isn't recommended although it is the driver linked to when you click on "Support & Drivers" on AMD's site?
