Hi there
another tack
If you are a gamer why not go for a better GPU. W7 should remove most of the intensive graphic stuff to the GPU vastly lowering the load on the CPU so you shouldn't need to OC it anyway.
As computers are evolving in this direction - expect the next generation of SSD'S to handle most of the entire I/O processing so the CPU itself will only have to handle various interrupts,"dispatch tasks", and manage memory (virtual and real) OC'ing will be a thing of the past with no real use any more.
In other words the CPU will just handle the task element ( a small central kernel) whilst all the other processes (I/O, network communications, video, audio etc.) will be offloaded to the various components with their OWN in built processors.
This means future CPU's could actually become much LESS powerful than today's quads and still produce much greater throughput on the system.
