Hey guys just brought my first iMac and made the switch to Apple! (Specs in signature). I Would like to install a Windows OS for gaming etc....? What version do you guys recommend? in particular would like to install Flight Sim X with Add-ons, and other various ongoing enhancements. I am curious about downloading Windows 7 RC 64 bit, what do you think? Otherwise will purchase Vista Home Prem 64 bit. Does anyone have experience running Windows 7 and Flight Sim X etc? Suggestions and Feedback welcome! Many Thanks!
