Mine: 256MB GeForce FX5200, 640MB RAM, but only a 1.3 GHz Pentium 4 in it.
I can run the game better than I had hoped, to be honest. I can handle Large maps without much difficulty, and the vast majority of the slowdown at the end of the game is from my old Audigy (no, not Audigy 2...just Audigy) finally giving out after loading 4 or 5 ages' worth of music changes and sound effects.
