Best Driver for a 5850 crossfire

Hi,
I would appreciate some help in driver selection for a pair of HD5850..
I already know thar 12.11 are good drivers for the 5800s.., but .. are this drivers good for a crossfire? .. or is better go for the last betas that includes crossfire optimizations and so on..?

Mostly I'am playing Tomb raider, dayz, hitman, DCS World series, mass effect series..

Thanks in advance!!

 

If u want to play tomb raider then install 13.3 beta 2....
The old drivers have problem with tressfx even on my single 5850..better to stay updated

 

Tried the last 13.2 b7 with Battlefield 3 and Crysis 3 and they work wonderful.

 

Tomb raider = 13.3 beta 2 drivers, good +% gain ( +12 fps for my 5970 with tress FX).

Playing mass effect 3 ultimate edition with full option.

 

Ok.. Thanks to all of you ... i really appreciate your help!!
Think.. i will go for the latest beta 13.3 beta2..

 

OR 13.3 beta 3, considering that just came out
