If your planning on running 5 clients on 1 machine, your going to have to get into a MacPro. The Mac Mini, dont even think about it. iMac? top of the line one will be very stressed. Macbook, nope. Macbook Pro, yes, but your pushing it.

I'm running my 30's a 2650x1600 resolution, and the 20's at 1680x1050. If you plan on running large resolutions, plan on getting the Nvidia 8800gt or the Ati HD3870, for the Mac Pro. You need the horsepower of either of those cards. Since the WOTLK expansion, and the 3.0.x patches, the graphics have been upped..... and frame rates have dropped. I'm running 2 of the 8800gt, and i have to turn some of the graphics settings down. I used to run everything maxed out before.

I'm praying that the 10.6 Snow Leopard version of OSX will pave the way with new graphics drivers to i can move up to a HD4870 or GTX280 card for this machine cause it sure needs it. Large resolutions suck the horsepower out of the graphics card.

Also plan on upgrading the typical 2gigs of ram to at least 8gigs. You will not have to do anything to the machine or operating system, as it will automatically handle it. you just have to buy the memory and stick it in.

Clonekeys/Clonedkeys works, but in OSX they seem to suffer keydropping/lagging. You will have to learn how to pace your self with keyspamming. There is NO maximizer/PiP type programs for OSX to use with WoW.

would like to use Keyclone, but refuse to buy Vista Ultimate x64, to be able to use more than 8 gigs, and 2 physical processors. OSX gives you accesss to those standard.
