NVIDIA’s really pushing performance with their GeForce 7800 line. Their GTX version’s the fastest card out there now but not everyone can afford the price tag. With that, NVIDIA’s also releasing a slightly slower GT version and we have one on our test bench today from Leadtek.

The Leadtek WinFast PX7800GT TDH MyVIVO Extreme, or another long Leadtek card name, is one of two versions of the GeForce 7800 GT PCI-E cards that they produce. Why is it “Extreme”? Well this version has a slightly better clock speed than the stock 7800 GTs. While the regular 7800 GT has speeds of 400MHz for the CPU and 500MHz (1000MHz DDR) for memory, the Extreme version has 450MHz for the CPU and 525MHz (1050MHz DDR) for the memory. There are 5 quad fragment pixel shader pipelines and 7 vertex shaders compared to the 6 quad and 8 vertex of the GTXs. So the GT’s reduced in a few areas, but not by that much. Everything else that the GTX can do the GT can do as well such as High Precision Dynamic Range Technology, CineFX 4.0, Intellisample 4.0, SLI, Pure Video, and so forth. The card also features 256MB of ram.

Physically, the board is a single slot solution with a reference cooler. The WinFast logo is over the cooling solution though. You might have seen a few of their cards that feature a grill cover on their fan but Leadtek has done away with it in this card at least. I was surprised at how quiet the fan is after the initial startup. I was afraid that it would be too loud but after the card settles down, it didn’t seem to spin up at all after long sessions of Battlefield 2. Combining this card with the ABIT AN8 SLI featuring the heatpipe cooling of the Northbridge and a quiet Zalman power supply provided a very, very quiet gaming session.

On top is the SLI connector that’s prominent in other recent NVIDIA cards. For video connections, the card has dual DVI connectors and comes with two DVI to VGA adapter in case you need to connect it to an older monitor. As the name suggests, the board also has a VIVO connection so you can connect a video source to be displayed on your computer through the card.

The GeForce 7800 GT cards need an external power connector even though it’s connecting to the PCI-E bus. So for that, there’s a six pin connector on the card itself. Included in the package is the necessary cable to convert the six pin to a regular molex connector.
