I've really been looking forward to The Sims 3, and now that they're told us that Mac + PC will be shipping at the same time (June 2nd 2009). I'm considering installing it on my iMac. I just have a few questions. First of all, it's a brand new iMac, 2.66GHz 4GB memory NVIDIA GeForce 9400 My questions are: 1. Will the game run good? (I'm used to playing The Sims 2 [with a about 8 expansion packs] on an old PC so I'm expecting anything will be better) Edit - EA has stated that this game was designed to run good on old machines, so I'm expecting it to be fine. And I'm only a casual games, play a few times a month. 2. Will having the game on my computer slow it down? (When the game is not in use) & These are the specs provided by EA "FOR MAC OS X * Mac OS X 10.5.7 Leopard or higher * Intel Core Duo Processor * 2 GB RAM * ATI X1600 or Nvidia 7300 GT with 128 MB of Video RAM, or Intel Integrated GMA X3100. * At least 6.1 GB of hard drive space, with at least 1 GB additional space for custom content and saved games * This game will not run on PowerPC (G3/G4/G5) based Mac systems, or the GMA 950 class of integrated video cards."
