I am a freshman in high-school. I have the white, 17inch intel iMac and I want one of the new iMacs. My problem is....which one should I get? I want one of the 24inchers....it seemed fine before but everyone seems to be doubting the NVIDIA GeForce 9400M graphics card that the first 2 come with. Is that not good? The one I have now is an ATY, Radeon X1600. I don't know how good that is compared to the 9400M one. Basically, I play WoW and Sims. Sims 3 is coming in June and I want it to look good. WoW is kinda bad on my computer now but it works ok I guess. So my question is....is the 9400M one fine? or should i get a better one?
