Ugh, it's that Time Again...

It is once again time to do the dreaded upgrade of a computer. Am I the only one who hated doing it? Maybe because I am poor? Anyway, I can upgrade one thing in my computer and I need to know what needs it the most. Here are my specs:

Windows 7 32bit
Intel Pentium Dual CPU E2200 @ 2.2GHz 2.2GHz
2gb RAM
Nvidia Geforce 9400 GT

I am thinking graphics card or processor. That or maybe I should just finally join the mainstream gamers and get a console, preferably the Playstation 3...But then I would have to get Battlefield AGAIN....ugh, this sucks.
