I'm trying to get some idea of the performance improvement I would get moving to a Mac from my current low spec PC. I'm thinking G4 Mac mini/eMac or iBook rather than anything G5. My current setup: Intel Celeron 667Mhz, Integrated graphics (82810 Intel Graphics Controller, what ever that is lol) 320Mb RAM. Windows Millenium Edition. It's 4 years old . I downloaded a screensaver called "flurry" for my PC....it hardly moves at all... the screen updates about once every 2 seconds. How big of a difference does having a dedicated graphics card make compared to integrated graphics?
