What should I upgrade next? *

My Current PC:

Intel e8400 - 3.0ghz dual core (Not overclocked)
2gb ddr2 ram cl 4
ATI radeon 4830
Gigabyte DS3L - p35 chipset
Vista Operating System
320gb hard drive
Deathadder mouse
microsoft keyboard
20+ inch widescreen LG lcd
wireless pci card for internet
500W power supply

Not sure if some of the stuff really matters; but im looking to play ARMA 2 and games like Crysis and GTA IV on higher frames.

What is your recommended next upgrade for me?

Your graphics card. What kind of power supply do you have?

500w power supply.

I would put more RAM in it and upgrade to windows 7 if you can. I would leave the CPU alone for now, considering a core2quad wouldn't do you much good at this point, and upgrade the GPU down the road if you still have that mobo.

The choice is clear: RAM.

Don't get more RAM unless you have a 64 bit OScole_793

I have 64-bit Vista - So 4GB ram would be effecient. 6GB ram overkill?

So far I'm thinking to get also get a better cpu cooler than the stock one so I can squeeze a little more out of the dual core e8400 3.0ghz.

I'll probaly get a 750w+ PSU and Windows 7 and then as people are saying get a 5850 or 5870 later down the road.
