I ordered two 8600s. Forsa 8600 GT 512MB DDR2 and Sparkle 8600 GTS 256MB DDR3. The Forsa had corruption in graphics and Sparkle's GTS will hang in 3D applications. Both are installed into Gigabyte EP35 DS3R mobo with a 600W PSU. Is it Nvidia's fault or the board partner's fault? If I'm not mistaken, Nvidia produce the GPU and boards and it's up to their partnerts to add in their own stickers and change the packaging? Btw both are made in China. Quite dissapointed with the poor quality control even both cards are low end and cheap stuff.
