Overall, the machine runs completely well and smoothly compared to my iMac G4. Everything is responsive. Safari feels like IE on a PC now. It's fast and smooth.
Halo and Rainbow Six surprised me. Looks like games could run decently without being Intel-optimized, although upon checking the Get Info on both apps, Halo does not have a PowerPC or Universal tag in parentheses after its name, but Rainbow Six says "Rainbow Six (PowerPC)." Odd...
Anyhow, graphics-intesive apps seem to be no problem, although Intel-ready apps will probably make these games fly!
Emulators need some Intel-ready binaries. SNES9X and Mupen are my playable emulators. I'll be waiting for updates, RB! 🙂
H.264 is not supported by the Radeon X1600's hardware just yet. Apple will probably have drivers ready. Until then, H.264 will stay a processor task and intensive.
Love my iMac. 🙂
If you have any special requests, post away.
