NVIDIA now offers new version 280.26 reference drivers, the first WHQL-certified drivers from the new 280 series for their GeForce and ION GPUs. There are drivers for Windows 7/Windows Vista, Windows XP, Windows Vista 64-bit/Windows 7 64-bit, and Windows XP 64-bit. These enable SLI technology on SLI-certified motherboards with AMD 990FX, 990X, and 970 chipsets; support GPU overclocking and temperature monitoring by installing NVIDIA System Tools software; update PhysX and HD Audio drivers, and more. Thanks Charles.
