對於目前如雨後春筍冒出的 DX 9.0c 遊戲，再加上 PureVideo, 6600GT 其實是比較好的選擇。
起碼爽度比較夠。

x-bit labs 宣稱 PureVideo 功能可以正常執行。只不過必須有 "special drivers" 及 NVIDIA DVD Decoder. (文中指出一些 AGP 的 6800 必須更新 BIOS 才能正常使用這個功能）
唯一缺憾，DVD Decoder 並非是免費的，感覺上到頭來還是被 nVidia 擺了一道。

X-bit labs can confirm that the PureVideo technology works on the GeForce 6800- and GeForce 6600-series graphics cards available in our laboratory, provided that special drivers and NVIDIA DVD Decoder is used. However, at least some NVIDIA GeForce 6800-series graphics cards for AGP bus require a BIOS update. Please keep in mind that different BIOSes are needed for graphics cards with different PCB designs.

NVIDIA unveiled its Programmable Video Processor in mid-April, along with the GeForce 6800-series of graphics processing units. The company, however, did not enable the PVP from the beginning and then even said the PVP of the GeForce 6800 was less advanced than that of the GeForce 6600, claiming that the former did not support HD WMV acceleration.
