Vista x64 on Mac Pro - Worth it?

[dimon1408]

Hi,
I've got a kick-ass 8-core Mac Pro and now I've come across a dilemma The problem is, I'm trying to run GTA IV but it's just painfully slow through Boot Camp on my XP SP3 x32. I've got a licensed Vista x64 disk, and I am thinking about using it. Can the regulars here recommend it or not? Do you think I'll have a better gaming experience?

PS. - I'm not using x32 Vista on my Mac because as I go into a game or even watch a Youtube video, the sound glitches and slows for a few seconds.

The irony is that the graphic detail in this console port isn’t exactly groundbreaking, yet it’s pushing our system harder that more notorious titles like Crysis.

This is true, yet somehow on my other PC (note - actually PC, came with Vista x32) the game manages to run so perfectly and smoothly on the same settings I use with my Mac. So it's something with the OS...
It's also kinda ironic that they get better fps on x32 machines...
