under a 32 bit OS, each application can only use 2GB maximum.
Thats address space - and your video cards ram uses that. DX9 applications also duplicate into system memory - so with a 640MB card (only one counts, memory doesnt add in SLI) you have 640MB as a maximum address spaced used, as well as a duplication of that memory.
WORST case, with every video setting cranked to the max using all 640MB of video ram - you'd have about 800MB left over for your game. I'd expect it to be more around the 1-1.2GB mark.
You know, I'm curious to know what would happen if you used a graphics card with 4GB RAM on it on a 32-bit OS - that would theoretically grab the whole address space, so would the OS even boot properly?
