Some people have stability problems with 3x512 RAM. Also, when you do want to upgrade your RAM later, which you would obviously up with sticks of 1024, you'll be stuck with three old 512s instead of two. I'd stay with what you have until you can get 2x1024.

I just went from 2x512 to 2x1024 a few days ago. Other than a slight increase in FSX, I haven't noticed it much, but I know it's good to have and I'll keep this new RAM even if I change the CPU or video card.
