I just installed Maya and oh my god it is slow - I realize that it is doing a ton of calculations on the fly to add light and objects, etc, but I can't believe that it would be that slow.

Adding a light source and choose "Display Selected Lights" took 3-5 minutes.

My machine is an Athalon 1Ghz, 704MB of RAM, WindowsXP

What are you guys running Maya on?
Is my experience normal?
