Ok thanks everyone. Sounds like I need to upgrade the power before I can see a significant video performance increase. If I go that route how do I confirm my current MB and other components can work with another power supply?
Be VERY CAREFUL with this proccess. I tried this once and fried my motherboard. Ask someone who knows what they are doing and make sure you have warranty. Some may disagree with me but sometimes to much voltage can destroy componnents.
