Interesting. There are advocates of the 158.24 whql, of the 158.45 and of the 160.x I'm using 158.24 atm and I dont have problems. I dont play any dx10 game yet and there'll be new whql drivers out before I will. I'm mostly playing Oblivion, medieval 2 and nwn2. The only demanding game is Oblivion, expecial with quarl textures and hdr water and weather mods. For Oblivion what do you suggest (vista x64, therefore i prefer whql drivers). I have seen 3dmark benchs, but a real game bench is better.
