ATI releases ATI Catalyst 9.8 for Windows 7 | XP | Vista

These improvements are more platform related – you will see gains of up to 50% in some titles (like Far Cry 2) when using a CrossFire solution with 4870 X2 or other 4xxx series in resolutions 16×10 and higher – you’ll see these gains mostly in CPU-bound situations. You will also see significant improvements in titles like HAWX, Crysis, Company of Heroes and World in Conflict. Link
