So I wanted to upgrade to 4 GB of memory & after talking to 3 different guys at Best Buy & getting all different answers & mistakes <sigh>, I decided to ask people & see what the majority says.

I do remember hearing several times in the past that anything more than 2 GB is worthless on a computer.

The last guy said b/c I'm on XP, even if I upgraded to 4 it wouldn't matter. It's DDR2. He said the computer will only fly if it's 4 & on Vista or 7.

I hope a real geek is out there to help
