32 bit is capped at 2.75GB - 3.5GB.
Correct, 64bit still holds speed advantages making it faster.
"A 64-bit processor is made with more advanced silicon processes, have more transistors, and faster speeds. This is currently where the true benefit of switching to a 64-bit processor lays."
"In a 32-bit computer, the width (or size) of the data buss is 32-bits wide. A 64-bit buss is twice as wide so the system can move twice as much data around. Being able to process more data means a faster system -- but only for specific things. Normal office productivity and web surfing will show no advantages at all, whereas graphics processing and scientific calculations will go much faster."
"Advantages when you install a 64-bit version of Windows Vista;
Increased memory support beyond that of the 4-GB addressable memory space that is available in a 32-bit operating system.
Increased program performance for programs that are written to take advantage of a 64-bit operating system.
Enhanced security features."
