Voodoo from Immortalmachines.com briefly goes over the current state of Quad-Core CPUs, and if it's even worth it for PC gamers.
"Beyond the price, is a quad core CPU useful in a PC Gaming rig? Well, if you use your rig like I do, it is used for more than PC Gaming. Sometimes I may be only playing a game but other times I there might be a TV recording in the background. Video recordings, especially live ones, are very susceptible to lack of resources which will result in loss frames. As a matter of fact, any type of audio/video encoding/decoding/transcoding can play havoc on the CPU. With a quad core, you have cores to spare... But this brings us back to the first point, is it worth it?"
