Hey guys, im planning on buying a laptop for school and to fulfill my multimedia wants in my spare time. I've decided on a laptop, but it's preloaded with 4 gb ram and of course Vista 64-bit.

I have only experience with 32-bit operating systems so i don't know any difference. If i got a 64-bit os, would any game / program be compatible with it without a hitch?

Gaming is light (call of duty 4/sims 2 wise) and programs would be microsoft office/itunes etc.

Thanks
