I have a 27' iMac mid 2011. I am considering getting bootcamp for it for the sole purpose of gaming. Will my mac even be able to play good games like Skyrim? I only have used about 145GB in my 1TB hard drive. I read somewhere that you should back your data up before downloading bootcamp. I don't have an extra disk, so is it even possible to back something up on the same drive through time machine? If something does go wrong will my Lion software or Windows office (which are the most important things on my mac) be ruined? My mac came with Snow Leopard but I got a free code from the store I bought for Lion software. I also used a CD to download my Windows office, so I hope if anything goes wrong neither of those will be affected. So is bootcamp a good idea for my specific mac and downloading it without backing it up? Thanks in advance.
