with my gf2 I got 3107 with 23.12 and 3115 with 27.42

You're not the only one that gets the drops with drivers past 23.12 The only improvement I notice is enhanced image quality which is nice Running Elsa Gladiac 920 (GeForce 3) @ 240/545 speed Get only about 8720 with 27.42 - Got 8936 with 23.12

Funny to see people installing betas aswell..
