Hi I have a unibody MBP 2.66GHZ/4GB RAM/512MB of 9600M GT GPU Option I'm thinking about installing a windows primarily for gaming. Basically the question is, should i go with xp pro? or vista? I play FPS games like TF2 and Left for Dead. Some of the other games I wish to play some RTS like Dawn of War2 and The Last Remnant. If the game performance in XP pro is much higher than Vista I would rather go with XP. but if it's more or less the same Id just go with Vista. Does anyone have any first hand experience on his issue? Any help would be great. thanks!!
