New Build w/ SSD Boot Drive, what do I need to know?

I'm building a new PC and am planning to use a 40GB Intel SSD as a boot drive with a regular hard disk for data. I'm using Windows 7. One of the things I keep coming across, particularly for a gaming PC, is how little space is left on the 40GB after the OS. Ideally, I wouldn't put but my most used game on the SSD. Everything else goes on the data drive.

But it looks like its hard to really make Windows do this. I see registry hacks for moving the ProgramFiles folder. I see other hacks for moving user folders either using symbolic links or other registry hacks (I'm leaning towards the links).

I also saw one recommendation to install Windows 7 on both drives and just boot with the SSD. But I'm not sure how that would work.

So my question - what set up do you recommend so that the majority of my data / installs go to my data drive while using the SSD hard drive for boots and a few choice apps/games.?

Is it more of a PITA than its worth? I haven't decided whether to open the SSD when it gets here or to return it.

Thanks for the advice!
