Introduction
Recently, we covered the launch of the new GeForce 7600 GT GPU, NVIDIA's new mid-range graphics card. It officially replaces the very popular GeForce 6600 GT, but will it be able to mimic the 6600 GT's popularity by offering the same great combination of low cost and great performance?
Today, we will find out for ourselves if the new GeForce 7600 GT will offer the same kind of value its predecessor did. To do that, we will examine the performance of the single card as well as two GeForce 7600 GTs in SLI. But first, let's take a look at how the GeForce 7600 GT compares against its predecessors.

As you can see, the new GeForce 7600 GT already has a large advantage over its predecessor in both fillrate and memory bandwidth (about 67.5% and 40% respectively). But that's not all. It also has two additional vertex pipelines. Coupled with a higher clock speed for the vertex processor, the new GeForce 7600 GT can process about 87% more vertices than the GeForce 6600 GT.
On paper at least, the GeForce 7600 GT seems like a very suitable candidate to take over the GeForce 6600 GT's reins on the mid-range market. We will need to confirm that with benchmarks, of course. But first, let's take a look at its full specifications.
