Notes
As far as we know, id has no plans to update the Doom 3 engine used in Quake 4/Prey to take advantage of multi-threading; Enemy Territory: Quake Wars isn’t listed as a game that will push today’s latest quad-core solutions. In any case, as you can see, the Core 2 Quad Q6600 performs just like the E6600 in this benchmark.
