Well, 8400GS is usually more than enough for normal office work.
What kind of work do you do? Normal excel, normal databank, powerpoint, or any special activities involving professional graphic software?
Are you using 2 monitors or perhaps more?
Thanks for replying. I'll be using Linux mostly with little/no special activities involving professional graphic software and a single monitor. I'll be using the cpu more extensively as i need to run programs. So i suppose as you are hinting that the 8400gs should be sufficient for me. I was just enquiring whether in the future any OS will come that will require more graphics capabilities.
