Which graphic chip is really a better one? In nVidia website, they put 9600GT as a higher level chip compare to 9600GSO. But some website has benchmarks that 9600GSO is slightly faster than 9600GT. So which is actually the one to go if you were me?
If you are running at a resolution of 1280x1024 or lower then the 9600GSO will do just as good or better than the 9600GT. If you do get a '9600
GSO' get the 8800GS (same exact card with different name) because the 8800GS is only $100 after rebate on newegg vs. $120 for the 9600GSO.
Oh and AA stands for Anti-Aliasing which is used to remove the appearance of rough edges on objects in games.
