The PC that I have right now is.... 2.66ghz Pentium 4 with a 533mhz FSb Geforce 6600 128mb pci-express video card 1gb of DDR2 RAM The Mac I will be getting is the 1.42ghz mac mini and I will upgrade the ram to 1gb (can it go any higher?) My main concern is will this mac that I get be able to compare to my pc when it comes to multi-tasking? On my PC I always have atleast a couple windows open in firefox, msn messenger going, and I have my World of Warcraft game going. It does slow down sometimes but for the most part it handles all of this just fine. I know this mac will most likely not be able to handle as many things at once but what can it handle???
