There is NO reason whatsoever to be overclocking any dual-core or quad-core CPU for this game. Unless you enjoy CTD's, than have at it. Overclocking was really made for single CPU's but with Dual-Core you litterally have 2 CPU's sharing the load. Quad-core is 4 There's a rule called "Moores Law" that CPU clock rates cannot go higher that a certain rate. So multi-cores share the load. A quad core can run WWIIOL while doing some Photoshop editing and maybe doing some recording with Protools. It aint the CPU people, it's the GPU, the RAM, the connectivity and the hard drive that are the main culprits for onlne gamers. Overclocking aint going to do doodie for you with this game.
