Ram / Impact

Whats up everyone, my first time here in the memory forum, just have a few questions.

I was at the computer store the other day and I heard some guy telling a few kids who wanted ram that windows only supported 1 gig of ram that 2 gigs would be a waste... Im assuming thats bs because lots of home pc's and server applications have well over 1 gig. Is this a common myth?? Was a older version of windows capped at 1 gig?

And my second question would be, how ram intensive is 3dmark05, would a second gig of ram increase the score by a large margin???

Some review sites have found lower performance going with 2GB RAM rather than 1GB. 3GB is worse still and 4GB is intolerable. That assumes that you aren't using applications which actually NEED 2GB of course. Tom's explained the phenomena but I don't remember the explaination. Supposedly 64-bit processors aren't affected at these levels.

This is a half-myth. It is related to a (patchable) issue in Win98 where it would not utilize system memory past 1gig.
