Not only am I new to MacOSX itself, I am even more new to Windows on a Mac and am currently looking into that now. I initially purchased my MacBook Pro with a 500GB Hard Drive in hopes of one day dedicating half or more of that to Windows in order to play older games on it. I have a few questions. 1) Is Windows on a Mac any different than a sole Windows platform in terms of compatibility of programs and games on it? In other words, would I essentially be able to install anything on my "Windows Mac" that I would be able to on a traditional Windows computer? 2) How would I necessarily go about things like Drivers with all of these integrated parts and such? What important things will I need besides a simple Windows OS disc? 3) What bit should I be concerned with purchasing? When I was a PC user, I was always told that "64 bit is better for gaming" but I'm not so sure if I should go with that if my version of MacOSX is 32 bit. Would that be a concern or problem? What would be ideal to go with in terms of 32bit vs. 64bit just for gaming? 4) This is probably the most important thing to address, and sort of goes hand in hand with #3. If I did go through with this, the question is simple, which version of Windows 7 should I get? I am aware that they have all of these versions such as Ultimate, Home, Professional, whatever, and different pricing on each. I was wondering exactly which would be the best purchase for me if I ONLY want to be gaming on the Windows side? I mainly want the most sensible Windows OS for gaming. I do not care about having the most graphically advanced games or anything - so please take that into account when suggesting 64bit or 32bit. Whichever is easier on my system, I would most certainly prefer. I am looking to play games from earlier on and could care less about keeping up with releases - that is why I am doing this on my Mac in the first place. I apologize for the lengthy post but thank you to anyone who responds and offers some helpful insight.
