Still getting familiarized with ATI's drivers but how do you force options to a particular game such as AA and all that. In nvidia you just select the .exe and choose what options you wanted to force.

I'd recommend first of all to have the latest drivers installed as it supports more games via additional profiles, they're not as open and accessible as on NVIDIA hardware however so being up to date is very important.
(Even the beta release 9.10 drivers released two days ago is a good alternative but the official WHQL 9.10's should be out fairly soon anyway.)
Then you just untick the application controlled box and set the options to what you want, same with setting VSync to force off, however ATI goes for compatibility and stability so it'll still bend to what the game says than what the drivers say if it's set in the profile options, especially disabling VSync (EDIT: Outside of the in-game options.) is a bit wonky with newer games albeit AA and AF works pretty well when forced.
(I do use application controlled AA but the mode is set to Edge Detect due to the superior visuals and I also enable Adaptive AA for 2D objects and similar, Edge Detect needs at least 4xAA enabled in-game to work and then it will be comparative to roughly 12x AA samples, uses the stream shaders as well so more recent hardware manages it just fine performance wise.)
Catalyst AI needs to be enabled as well, on normal it'll use game specific profiles and optimizations plus it's needed for X2 cards crossfire to be enabled, on advanced it'll use more advanced optimizations that can reduce image quality a bit and it'll also try to force AFR crossfire rendering, disabling it only uses compatibility "flags" for the various profiles without optimizations and special features so it's not recommended.
(Special features being stuff like forcing AA in Oblivion with HDR enabled or UE3 titles with deferred shading used, renaming a EXE works pretty well if you want to try forcing AA or improving Crossfire performance as well, at least until ATI updates their drivers or rather the profiles within them.)
Main problem is that NVIDIA releases beta and even SLI driver updates to cover titles much quicker whereas ATI releases hotfixes only for critical issues (Recent 9.10 beta 2 driver release for example is mainly to cover the 5700 cards but it is built on a very new 9.10 version and contains support for all current supported hardware as well.) other than that they're using a one driver revision per month schedule so some more recent games can take one or two months to be fully supported.
(Longer still on less popular titles, ATI seems to focus very much on the CCC and Windows 7 now as well plus of course the recent release of the 5000 model of cards, for example a new look for the CCC was added in 9.8 if I remember correctly and 9.11 adds a more improved power saving function for X2 and Crossfire configurations where the second card is turned off completely outside of 3D or "active" mode.)
