I am looking to upgrade my sawtooth G4 500 and am looking at the dual 800mhz, and the single ghz. I dont do photoshop, but I do use many apps at once. I also play games. I am leaning towards the dual 800 mainly because it will do nicely when I have lots of apps open, and have backlight running the screen saver in the background. But the games (except the few SMP enabled ones) will benefit from the faster 1ghz processor. The single processor is cheaper. I am torn about this. What games are optimized for multi cpus besides quake? I play warcraft, and I can barely play during large battles. Is 800mhz good enough to have relatively smooth battles (at least enough for me to see the mouse cursor to do spells, im not asking for a miracle)
