The old 1.5xRAM rule of thumb survives from Win9x and terrible paging code & system leaks. It isn't very relevant for anything recent.

As Dragon said, watch your peak vs. limit numbers and size accordingly. If you have enough RAM (peak below physical) then set DisablePagingExecutive = 1 and allocate a minimal amount of disk to the paging file. (ideally on another disk) This allows software to run that requires VM but almost eliminates swapping by the system. If you're a heavy Photoshop user you'll need to bump it up more.

DisablePagingExecutive is:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\DisablePagingExecutive

I usually don't start micromanaging VM until I have 768MB. You have enough to begin paying attention.
