@Luciel
That was a great opinion, I should have thought about that
I am using SATA now and maybe as Luci said, I installed too many programs.
@Luci
I take your sugguestion, I would go for Opteron 64 bits with 2X 512 DDR, maybe not DDR2 at the moment as AMD 64 bits not yet support DDR2. I need a good notebook as I have to traveled a lot now.
As why you can't played anything in your brother`s notebook, maybe it is beacuse he used onboard display card and shared a low memory as he intented to use his notebook only for work not game. If he had a good performance display card, playing games in notebook is not a problem at all.

I asked as I am curious and as Luciel said, maybe is the ATA IDE that caused the problem. Many people still buy ATA IDE, right? so many people still buy things that decrease in performance after certain years.
