I just ran a report on with everest, and, while reading it I noticed that it said my agp aperture size was 128mb. Well, I am running a 7800 GS with 256mb so I went into BIOS and changed the aperture to 256mb. What I am wondering is, will this make a significant difference? I just ran 3dMark01 and my benchmarks went up 1500 points, but what really does the changing of the aperture size do?
