P_T, there are so many inaccuracies on this page it's impossible to correct them all without my head exploding.
For example; 1) running a 32-bit OS doesn't effectively halve your CPU speed. 2) Dispite theoretical support for an astronomical amount of memory, actual support is a lot lower. 3) Win7 is a lot less of a resource hog than Vista, regardless of what version you're running (matter of fact, 64-bit systems need
more memory for the same operation).
Imho you're misleading or misinforming a lot of people.
