Nvidia has abandoned its unified driver strategy but did it rather discreetly. You don't want to make a big deal out of something that used to be the pride of the company when today you are not able to make it happen.
Unified drivers are history, and while we are expecting Forceware (we still like the Detonator brand better F.ed) 177.39, Nvidia has released a new Forceward 175.19 driver for Geforce 6, 7, 8 and 9 series GPU.
The new driver adds support for Geforce 9800GX2, 9800GTX, 9600GT, 9600GSO (renamed 8800GT) and Geforce 8300, 8200 and 8100, which are basically IGPs from Nforce chipsets.
It also improves performance and load times for Geforce 8 and 9 cards in some DirectX 9 and Open GL applications, and all as a result of improved Shader optimizer.
There are a few new Pure HD features for Geforce 9800 GX2, 9800 GTX, 9600 GT, and 9600 GSO, including Dynamic Contrast Enhancement, Dynamic Blue, Green & Skin Tone Enhancements and Dual‐Stream Decode Acceleration.
The driver fixed a lot of bugs, as well, and if you have XP or Vista and Geforce 9 or 8 cards you should go for this one. It supports single cards or SLI and if you have Geforce 6 to 9 card we suggest you get the new one.
You can download it here for Vista 32 and here for Win XP.
