Actually as the resolution and level of details increase 7800gs lead over 7600gt also increase - at 1600*1200 the gap is huge because of the 256 bit memory bus, but yes if you test only at 1024*768 there is not much difference between them! Main problem with 7800gs is price - the card is very expensive because it is a sought after item and considered one of the best AGP card from NVIDIA.
It does not seem that simple.
The issue with 7800gs, reference one, are low clocks. It is 375 core, 600 memory instead of 560 core and 700 memory for 7600GT. Yes wider memory bus helps, but the GPU itself is not faster despite having more PS/VS/TMU because of huge clock difference.
Also G70 is 110nm vs , G73 is 90nm, or 80nm in case of G73-B1. So not only it is hard to get any performance advantage from 7800gs because it is not fast enough to be practically used at those settings/resolutions where it may happen, but also it is hotter for no good reason.
I've had much easier time finding 7800GS then 7600GT locally, prices may be a bit higher because of "8" instead of "6", but not significantly so and availability is better.
There are different versions which are factory overclocked or in some cases use different GPUs, those are rare, expensive and better. There is also 7900GS which is significantly better, but also rare and expensive.
I got 7800GS too, out of curiosity, and my opinion is that all things considered 7600GT is actually more practical, especially if available at lower price.
I am going to build a fun S939+AGP system, already got the important parts, so may be i'll bench a bunch of AGP cards i got on that for fun and post it. The only thing i am not sure about is which games have built-in benchmarks and which of them to use...
