NVIDIA PCI-Express GeForce 6800 GT

PCI-Express video cards have been available for a little while now, but the high-end cards are not widely available yet. ATi's Radeon X800 and X800 XT cards are starting to show up on e-tailers' virtual shelves, but the newest NVIDIA card you'll find in retail form is a GeForce 6600 GT. Demand for PCI-Express cards probably hasn't been really high yet, though. However, now that nForce4 is about to hit the streets, I'm sure we'll see a spike in demand.

We have only seen a couple PCI-Express cards around here at Bjorn3D so far. The first was the Albatron GeForce PCX5750, which is a mid-range card from the previous NVIDIA generation. The second card to enter our labs is an NVIDIA reference GeForce 6800 GT, and that's what I'll be covering today.

There are no major differences between the PCI-Express version of the 6800 GT and its AGP brother besides the interface. Just like its AGP brother, though, I do expect the PCI-Express 6800 GT to be a good overclocker, reaching Ultra speeds with little effort. Read on to see just how a PCI-Express 6800 GT performs and to get an idea of how a PCI-Express 6800 Ultra might perform.
