RIght along these lines is my personal experience with the new starcraft/diablo, aka Warcraft 3. If you can actually get past the bugs that people have been encountering, this game is an excellent stress test. My oc'd system was rocksteady with anything I threw at benchmark/stress testing wise... at least until I played WC3. The game would crash out to the desktop complaining until I went into the bios and dropped the fsb by 2Mhz (157 to 155). I think this may have something to do with the programmers not writing the best code that they could've but regardless, it found an issue with my computer that until then had only appeared rather sporadically and infrequently, and never in any previous stress tests (so I had just dismissed it as Windows caused). Another good game to stress a system with is Civ3, altho this has been out longer.
