Asus EN7900GS TOP

1. Introduction

Asus, as a respectable VGA manufacturer has introduced its own proposal for the Nvidia 7900GS platform. This time, Asus hasn't exactly followed what other manufacturers have done, but rather, introduced new levels of performance with the EN7900GS Top VGA card. We compare how this card performs against various 7900GS VGA cards and how much performance can be gained by pairing two EN7900GS Top in SLI mode.
