Sorry if this has been covered, I'm sure it has. I have zero time lately to read over the posts. I am deploying to Kuwait for the summer. I am looking at buying a 24" iMac 3.06G when I return. I have heard mixed reviews about what is the better GPU, its seems both have issues (GT130/ATI4850). This will replace my G5 iMac which is going to my mother....going to get her hooked on Mac. I will do "some" gaming...Diablo 2 and such, the rest is documents for work, college courses.....etc. What's the consensus?
