3. The 7800 GS is no faster than a 7600 GT.
Unless u want to overclock.
The 7600 GT has 12 shader/texture pipes but has a 90nm process.
The 7800 GS has 16 shader/texture pipes but has a 110nm process.
So their core performance is arond the same at it's maximum overclock.
Howeve the 7800 GS wins because it has twice the memory bus.
Its all explained in my sig for anyone else who wants to see exactly what im talking about.
