TRENDING NOW: NVIDIA acquires Valve, announces Half-Life 3 release for 2016

nVidia's next big thing - GeForce 7800 GTX (Part 1 - The GPU and AIB Plans) - Specifications

Today nVidia has taken the wraps of their newest GPU, the GeForce 7800 GTX formerly known as the "G70". The new graphics card is much more powerful than their former flagship 6800 Ultra and uses less power and only uses a single slot cooler design which is quieter than the previous design. Read on for all the juice on nVidia's new bad boy as we take a close look at the specifications and the card itself along with what some of nVidia's partners have already told us.
