AMD's Catalyst 13.2 beta drivers got leaked, I read up on them and saw that people were getting better performence in BF3, GW2, FC3 & smoother gameplay in Skyrim, so I decided to try them out (after just installing 13.1 two days earlier) and I got 153 more marks in 3dmark11 and my WEI graphics score jumped from 7.8 (13.1) to 7.9 (13.2b) so AMD is def on to something with these

Do post what results you get if you do decide them

Here is the link below, since they are only beta - TRY AT YOUR OWN RISK!!
