All, I just bought the 27" iMac with the quad core i7 setup from my local Apple store. Its awesome. I'm thinking about putting windows 7 on for dual boot, in case I want to do windows-specific gaming. While I could partition my 1 TB drive (to, say, 600/400 or 700/300 in favor of the iMac side) I was wondering about the possibility of external drives. Would any modern 2.0 USB-powered external hard drive be adequate for installing Windows 7 on, and would it work specifically for gaming? Or am I better off just doing the partition on my internal drive? What about firewire 800? Etc. Thanks!
