I just bought a PowerMac G5 with the bluetooth bundle (keyboard/mouse) and had a question about performance. I have tried out both the iMac G5 1.8 GHz and PowerMac Dual 1.8 GHz at the Apple Store, and the iMac seems sluggish compared. Is this due to RAM? The iMac only has 256 where the PowerMac's they have there have 1 GB. I am planning on ordering 2 512 sticks of Crucial PC3200 RAM to put in my PowerMac. Should I expect it to run as smooth as the dual 1.8 with 1 GB of RAM? Of course the dual is going to be faster rendering, etc, but I am basically talking about everyday use.
