EVGA GeForce 7800 GS AGP

eVGA's card uses a single-slot cooling solution. The cooler, which covers both the GPU and the memory modules, consists of a fan and aluminum cooling fins covered by an acrylic faceplate. The graphics chip provides support for Pixel Shader version 3.0 and HDR rendering. Our test sample was an eVGA "Superclocked Edition," meaning it runs at increased clock speeds right out of the box. Thus, the GPU is clocked at 460 MHz, while the memory frequency is 1350 MHz. Thanks to its increased clock speeds and 256 MB of video memory, the card is ideally suited for current 3D games. Its target price is about $299.
