What hardware upgrades do you suggest?

[Zorbtek 0]

I'm thinking of upgrading my PC to run ArmA better but I'm unsure as to what I need.  I'm thinking it's RAM, but I'm not sure.

My processor is - Pentium 4 1.6 GHz

My RAM is - 512 MB

My graphics card - Radeon X1300

As you can see, I have an old computer that is crying for upgrades.

I went to "Can You Run It" Sys req lab and it says:

Minimum, I only fail processor wise

Recommended, I fail on RAM, Processor and graphics card (but I'm not too concered about graphics, I'd just like the game to run smooth)

Any suggestions?  Am I better off upgrading my RAM or processor?

I'm limited on $$$ so I need to choose between the two unfortunately
