Does FSX benefit much from more than 2GB?

Anyone think 64 bit XP or Vista helps>with anything - worried about the driver support etc? Driver support for Vista 64 and XP 64 are pretty good now, no problems here. I actually use XP64 on a 3 year old A64 laptop and Vista 64 and XP 32 dual boot on my main rig, next time I format I'll either go Vista 64 exclusively or dual boot XP 64 and Vista 64.
