I just installed an Radeon HD 6950, upgrading a Radeon 4850, but I'm seeing no difference in frame rates on my games. I've updated all my drivers, flashed the motherboard bios, and done clean installs to no avail.
Is it possible that my power supply is not providing enough wattage (it's 500W I believe) and therefore the GPU is running at a slower clockspeed? Or would the computer just crash if it wasn't getting enough power? I'm having no stability or overheating issues.
Thanks in advance.
