My personal favorite are 100% silent videocards. Devices like the Asus EAX1600XT Silent/TVD/256M/A videocard won’t eat up the 8GB/s worth of bandwidth the PCI Express x16 bus has to offer, but this passively cooled graphics card strikes a good balance between price and 3D rendering power. The Asus EAX1600XT Silent/TVD/256M/A is supported with 256MB of GDDR3 Infineon memory, and the software package that comes with the Asus EAX1600XT Silent/TVD/256M/A is strong.
