I'm a PC user considering switching to Mac. Been looking at all my options and since I already have a viable Monitor and sound system, my 2 choices were the mac min and mac pro. (big difference I know) Going for the single Quad core looks like a great option for me, because of the price. However, I dont have much experience with these Xeon processors. Would the single quad be enough for running iLife well and some casual gaming (LOTRO, some older FPS). I don't have a heavy gaming need but would like the flexibity to use the apple software with some gaming for a break. -$500 for the single processor has got me ready to order my first mac today, am I be mislead? Should I be getting the Octocore? Or is that too much for someone not doing professional things?
