Ok , i had an desktop computer, i never bought more then 1 GB of RAM because when i was looking to the stats it seems my PC wasn't consuming more then 600-800MB with photoshop opened , yahoo messenger opened , msn messenger opened, lot's of youtube sites openes (in firefox it's true) , php editor opened,etc... my desktop computer it's an intel one then i bought one AMD-64 bites Acer Laptop , I just said i never had an AMD in my whole life, so i will like to try one... and guess what ? this laptop seems to eat ram as hell ? why is this happening? because of the x64 CPU ? bcause it's AMD ? because laptops have a slow hard disk/video card?
