Well, the restriction a pump has to work against will effect it's output, both pressure and flowrate. Martin's Flow Rate Spreadsheet is an excellent tool for determining these effects.

You'll also need some information on how the block(s) and rad you plan on using perform at various flow rates. Here's a good guide on how to determine what you need to know.

And, of course, searching these forums will answer pretty much any other questions you may have concerning watercooling.
