Leadtek WinFast PX6600 GT TDH

Leadtek’s WinFast PX6600GT TDH is a by-the-book implementation of nVidia’s GeForce 6600 GT. The board’s GPU and 128MB of GDDR3 memory are clocked at 500MHz, as per nVidia’s reference design. As such, it can’t compete with Sapphire’s 256MB Radeon X800GT—at least not in terms of games performance.
The PX6600GT lagged the Sapphire in most of our gaming benchmarks, including Doom 3, typically a strong point for nVidia-powered cards. On the other hand, you can install a pair of these cards in an nForce4 motherboard, a feature that the ATI-powered board won’t be able to match until CrossFire reaches the market. And when it comes to MPEG-2 Decoding, Leadtek’s board beats the living snot out Sapphire’s—a major consideration if you’re looking to output video to TV.
