As a fair amount of other people appear to have decided, It's time for a new build and Sandy Bridge fits the bill. Scan Basket I'm pretty confident about everything except the case, mostly due to cooling concerns. The extra fan is for the side panel of the Define R3 to improve airflow to the GPU, leaving the rear case fan to deal with the OC'd 2500k. Hopefully this will provide adequate cooling under load while keeping the system quite quiet when I'm not gaming. Suggestions are gratefully appreciated!
