Introduction

Many consider the 7800GTX launch some months back to be one of the most successful launches in Nvidia’s history. Unlike a certain Canadian video card company we won't mention, there were no paper launches and the day that the reviews came out on the internet was the day that consumers (albeit those with a lot of money to spend) could go to their local computer store and pick up one or two of those cards for use in their own rig.

The reviews rolled in and the results were nothing short of stunning. Nvidia had, for the time being taken the performance crown away from ATI in both the single card and SLI dual card configurations. At that time, it seemed that ATI had a little of a marketing nightmare on their hands. The r520 had been delayed countless times and Crossfire was nowhere to be seen. Enter today, Crossfire has been released (although to this day, it's impossible to buy one in stores) and the r520 is on the horizon (at least in terms of reviews). That doesn’t mean that Nvidia’s partners have been resting on their laurels though.

No, they’ve been working on improving the already fast 7800GTX and making it faster. Leadtek is one of those companies. Traditionally, Leadtek has had two versions of their video cards, a “normal” version in which the cards were clocked at stock or slightly higher along with an “Extreme” version in which the cards had the living bejebus clocked out of them. The 7800GTX is no exception and today we’ll be looking at the Leadtek PX7800 GTX TDH MyVIVO Extreme, which for the time being is Leadtek’s fastest card and arguably one of the fastest cards in the world.

The 7800GTX has traditionally been a single slot solution, but Leadtek felt that the higher speeds of the card warranted a better HSF and thus they decided to create a dual slot solution that would offer a larger fan with a lower RPM. Those of you in the 3d graphics world will recognize this as the heatsink that comes on the Nvidia Quadro line of cards. Intended for the workstation world, those cards costs thousands of dollars and thus, ensuring that the cards keep working is of the utmost importance. For retail consumers of this card, that means that one need never worry about the cooling performance of their card. The added benefit of course is this VSF will be quieter than the already quiet (for a stock VSF fan) 7800GTX.

Unfortunately, the negative is that Leadtek's 7800 GTX is one of the few with a dual slot cooler. The stock heatsink is (impressively) a single slot unit.

In addition to the large fan, the larger VSF also has heatpipes on both ends of the card that help transfer heat to the rest of the radiating fins which help immensely with cooling performance. Also visible is the SLI connector for those who need to game at the highest resolutions possible.

Heatpipes would be useless without some good radiating fins and thus these can be found at both ends of the card. Note that the 7800GTX, like all fast, modern video cards will require the use of a dedicated PCIe power connector. Those without this connector on their powersupply need not fear; Leadtek includes a 4-pin molex to 6-pin PCIe adapter in the package.
