Luxury. Appearance. Love. And no virus.

It's better for multimedia actually. But frankly PC is more bang for buck by far.

I wish to switch to Mac myself, but if your rig is used for games, stick to PC.

Maybe I get both, since my economy now quite comfortable.

Typical Windows user. Vista is way less secure compared to OSX. Its a fact , if you say Windows 7 - I would agree. Every OSes they are flaws ,what differs with OSX is that Darwin (the kernel and most of the part of the OS are open-source compared to close source counterparts).
64-bit support in OSX was there for a long time ago ( http://www.appleinsider.com/articles/08/10...the_kernel.html ). Don't get me started on x86_64 and PAE. OSX makes use of PAE , again thats why its possible to have MacPro up to 32GB running on 32-bit (however due to kernel limitation , there are few limitations. It wasn't possible for 32-bit , even with PAE turned on to address. This is because of the nature of the WIndows OS , thats why Windows released 32-bit and 64-bit version.

The reason why it runs better goes back to history as it started it for mac and people still have to say that it runs way better then in OSX. Its history, just like how Windows is now currently.

OSX makes use of graphics card very well , now with OpenCL (aka CUDA) , programs can take advantage of GPU power in Macs to do things faster. PC users have it more , but lets see how developers use it in Mac !
