Which part should I upgrade?

[eggsaladbob]

My PC is getting outdated and I'd like to start upgrading some parts. Here are my specs:

Video card: NVIDIA GeForce 9600GT
CPU: Intel® Core 2 Duo Processor E8500, 3.16GHz
RAM: 8GB
Motherboard: ASUS P5N-D

Which of these do I most need to upgrade? Is it possible to upgrade some but not all or does everything need to be improved?

Thanks.

You need to think about a new build.
