That's true; 32-bit processors only have so many address lines, so the largest amount of memory they can see is 4G (Poser...I think...can only see 3, and that with some extra typing...;)
So if it has more than 4, it's likely a 64 bit.

You can go into the Control Panel and find out what sort of chip you have (usually if you see a sticker on the computer with '64' in it, you're good), but I'm not sure where it is in Win 7.

I wish I'd said that.. The Staircase Wit
