I have been running WoW in my dual PowerMac G5 since 2004. Everything is running fine, but the last expansion (Lich King) added some areas that seem to have heavy requirements and the FPS is lowered quite a bit. The degradation in performance was annoying enough that two years ago I upgraded RAM to 6GB, the OS to 10.5, and the graphics card to the best I could get for that configuration (ATI Radeon X800 XT). Even though things got better, it did not resolve the issues completely. The next suggested upgrade was to change to a new CPU architecture (Intel) which will improve Open GL performance as well as the opportunity to upgrade to the "faster" OS 10.6. I have a chance to upgrade my machine in the upcoming Holiday season. So, I was wondering about the most recent hardware. Is a Mac Pro overkill just to play WoW and basic photo/video editing? Or will a high-end iMac be sufficient for the next 6 years? Thanks!
