Sorry if what i say discourages some other people but i have to say it anyway. I have a windows 8 64-bit os on one of my hard drives and a windows 7 64-bit on my other hard drive. - I have two different ones because i like to have to option of tweaking certain things about windows 8 with windows 7 files, as in the start menu, also i do not recommend that you try what i just said - Back to the topic at hand, I definitely love windows 8 over windows 7 any day! The os is faster and the only reason people do not like windows eight is because of two reasons: 1. the start menu is a little hard for noobs to understand ; and 2. They have never actually tried it themselves and just believe what they hear from other people! Overall i say that you should use a windows 8 os for gaming, especially with MC.
