Okay, so I love the sims and I haven't played since Christmas. The reason is that I had a PC and the sims 2 but then when I got my iMac the game was for PC and not mac. I decided not to buy one for mac knowing that the sims 3 was out coming soon. the specs on apple say: -Mac OS X v10.5.7 or later -Intel Core Duo processor -2GB of RAM -6.1GB of free hard-disk space minimum (with at least 1GB of additional space for custom content and saved games) -128MB of VRAM -ATI X1600 or Nvidia 7300 GT or Intel Integrated GMA X3100 -DVD drive What i have is the 20 inch, 2.4 ghz c2d aluminum iMac. With 4gb of DDR2 RAM (not newest model that was released in March) -i got 10.5.7 yesterday -have a core 2 duo processor so its more then ample I'm assuming -i got 4gb it doesn't specify DDR2 or 3 so i gonna say I'm okay -got the hdd space -128 mb of VRAM (virtual memory?) no idea how to tell how much i get so I'm gonna say im good -i have the ATI Radeon HD 2400 128mb graphics card. will this be supported? -dvd drive of course. aside from all that hoopla my real question is not weather it will run (assuming it will) but how smoothly will it run. i dont do lot of gaming, the sims is really the only one i play. i want it to run well and on a fairly high setting w/o lag. is this possible? or am i gonna have to get the sims 2 to enjoy it Thanks!
