for every question asked there are more questions given...
so here we go.
In general, when selecting a video card strictly for a gaming purposes I understand that the architecture is increased with the numbers...kinda.
Example: a 6800GT is equal to a 7800GT as to a 8800GT these are big jumps in improving your video experience.
now lets say I have a 7800GT and I want to upgrade to 9600GT I have been told that that is going down the evolutionary scale and that is not improving performance it is decreasing it.. is that correct?
also all things being equal what is the most important specification the ????Mhz GPU Clock Speed or the ????Mhz Memory Clock Speed?
The G80 had a wider bus (320 on GTS 384 GTX) but low core clock because of die size. When they changed over to G92 they made a GT that was faster than old GTS and a GTS that had the same speed as GTX. Why at that time they did not use the 9xxx definition for those cards nobody understands.
The G92 is a very long living GPU still in the GTS250
