Is there a significant difference from 512MB to 1GB in RAM?

I have a HP zv6000 and I was wondering if there is a notable difference from going to 512MB to 1GB. My computer loads up slow, slow to load programs, and some of my games lag at intense intervals (no it's not a spyware/adware/virus problem). If there isn't a notable difference, then I'll probably invest into a gaming laptop.

You can also consider having a graphics card with more video RAM in it if you go for a new one.

Upgrading to 512MB to 1GB can be considered only if you have a good processor in your laptop. Or else, go for a new one with more RAM, HDD Space (preferably SATA), Dedicated graphics card with more video RAM will do good with games.
Yes I believe so !!!
Yup. 512Mb to 1G makes your unit run 30% to 40% faster when loading programs and switching from one program to the other.

Hope that helps you.
512Mb x2 = 1024mg (basically 1GB) easy math... which should give faster response. Also need to check on how many 'un-needed' apps maybe running after original start-up. Hope this info maybe helpful.
this will help until you decide
