ram vs. bit question

i dont exactly know what im talking about, but from what ive heard, a 32 bit system cant handle more then 4 gigs of memory at one time, this is pressing for me because im buying 8 gigs for a new computer, but if its a 32 bit OS is there a point in buying all that ram?

HAY GAIZ I don't exactly know what I'm talking about but I'm buying 8 GB of RAM.  I don't even know WTF OS I want to run, or maybe I do but I've already decided to buy all this fucking RAM even if the OS can't use it.  Is there a point in doing so?

Sorry OP, but you need to PLAN MOAR.
