>>>Incidentally, I only see 3.25GB of that 4GB memory because of the way 32-bit systems address memory. There is something called PAE that would allow me to see all of it, but NVidia doesn't support that. Even then, Vista 32-bit would only see 4GB max. The 4GB barrier (f.k.a. the 640K barrier) and 64-bit might be closer than we think.

Documented? Maybe, but vendors aren't exactly advertising the limitation. I knew about it going in, but as more people start buying systems with 4GB, they're going to be in for a surprise. Unless vendors turn on PAE, most people aren't going to know about it. 64-bit is the ultimate solution, but I hear driver support is bad right now. I'm not going to risk running it yet, but eventually I will.
