I have a Windows server running x32 2003 standard, and upgrading to x64 isn't possible right now because of software compatibility. We already have 4GB ram installed, but that is constantly maxed out. I was thinking about investing in a top-end SSD (Like the intel extreme), and use it as a dedicated disk for the paging file. I know its not quite the same as increasing memory, but I figure it will minimize the effect of the server always swapping memory contents in and out of the paging file. Thoughts?

Also, if you think this is a good idea, what SSD would you recommend? I'm thinking anything 16GB or higher is fine. I've heard good things about the Intel SLC, and Mtron.
