I just checked up on it. I might have been a little too fast. Sorry my mistake. It's true, however, even if you do have 4GB installed, and are running with 1024MB on your graphics card, it shouldn't be a problem. You would just not be able to use them effectively, or to their full capacity, whatever you prefer.
I would recommend, in light of these facts, that you move on to a 64bit OS if you have 4GB or more memory installed in your system, since it would only hold your system back if you stick to 32bit. And since 64bit can handle adresses up 16.384PetaByte, you wouldn't run into that problem in our lifetime.
Thanks to Rastalovich for correcting me
