Hi everyone, was thinking of upgrading my GPU to a Radeon HD 6850. I hear that you need a minimum of a 500W power supply. However, I don't have power hungry specs. Does the fact that I have only 4GB RAM and a Dual Core Processor mean that I can cope with my current 400W supply for the HD 6850. Thanks In Advance.
