Thanks to baconian at the Idle Forms for pointing these out. Majesco has released the system specs required to enjoy Psychonauts on your PC.
In short, at the bare minimum you need a 1.0Ghz Pentium III or AMD Athlon running Win98SE or better, a 64MB GeForce 3 or Radeon 8500 or better, and at least 256 MB of RAM. Full minimum and recommended system specs below:<:MORENEWS:>

Both of those specs are pretty reasonable assuming you've bought a somewhat gaming-ready PC in the last few years. That said, if you haven't updated your PC since Escape from Monkey Island, it's time to pay a visit to your favorite parts store or website.
These specs aren't surprising thanks to it being built originally as an X-box only title. Many games built for the X-box (and/or other consoles) then ported to the PC keep fairly reasonable specs (i.e., systems even 4 years old). Halo, Bloodrayne, Armed and Dangerous come to mind, but I'm sure there are others.
