If you want it to run really great.. You would want to look into a 64 bit cpu and a x800 and higher or a 6600 and higher video card.
But... Your current specs look fine and you'll be able to run the game on high with good performance.
I got mine working today.. I'm quite impressed also.
In the near future, I will be making some videos of the game.
I also run the game on High settings with no problems.
AMD Athlon XP 2400+

Heh.. Well, I picked up my copy of Black & White 2 last night.. Got home, tried to install it, kept getting Corrupted Sound files on CD2.
Said to try re-installing. After a few tries, the sound files stopped happening.
After CD2.. CD3.. and on CD3 I kept getting Catastrophic Failures blah blah...
I was browsing FilePlanet for some game demo's and I came across this.
