I will be joining the PC to Mac community soon and getting a new 27" iMac. One thing just struck me though. I have a Linksys wireless router. Will this be compatible with my iMac or will I need some new piece of hardware? Also, coming from a couple of crappy Dell computers that never really ran Sims 3 well at all, if I go with the $1999 27" i5 with 4 gig of RAM, will I finally be able to play my Sims with high quality graphics? Any input is appreciated!
