All benchmarks were run with the driver image setting configured to High Quality, with the exception of Far Cry which was set to Quality. The highest quality graphics settings were enabled in each game with the exception of water in Far Cry, which was set to Very High as opposed to Ultra High.
Update: A bug in the application profiling system resulted in the benchmarks, with the exception of Doom 3, to be run with a Quality image setting as opposed to High Quality. The bug is a result of the application profile image setting, which was set to High Quality, failing to override the global profile image setting, which was set to Quality. NVIDIA has mentioned this problem in their ForceWare version 77.77 Driver Release Notes. To ensure that settings will work for your application, NVIDIA recommends that settings be changed using the global profile as a temporary workaround.
Image Setting
Take a minute to look over the following benchmark results. You will find that in most cases the GeForce 7800 GTX met or exceeded the performance of the GeForce 6800 GT running in SLI.
Benchmark Results
The results with HDR enabled in Far Cry are by far the most impressive for the GeForce 7800 GTX.

And finally a few benchmarks with 8XS antialiasing enabled, which became practical to use in newer games when SLI became available.

CONCLUSION
Opinions will be formed that the GeForce 7800 GTX is only a minor update to the previous generation GeForce 6800 Ultra. While that depends on what the definition of a minor update is, I believe that the GeForce 7800 GTX represents a significant technology update. It runs faster, it renders higher-quality graphics, and it consumes less power. These benefits are certainly not indicative of what NVIDIA would achieve by only "tweaking" the architecture of the GeForce 6 Series.
