This is taking the p**s:

Basically:
8800GTS 512MB to 9800GTX to 9800GTX+ to GTS250
AND.... WAIT FOR IT...
8800GT to 9800GT to GTS240
Basically the major differences between all of these GPUs are:
1.)The 65nm to 55nm shrink
2.)Higher clocks
3.)A different BIOS
I think I will stay with ATI. Even their change from the R600 to RV670 was bigger than this(512 bit to 256 bit memory bus,55nm shrink,DX10.1 instead of DX10).
