I have a question about my power supply. I know no video cards are available yet, but I wanted to buy a new power supply so that I could run an AMD 6800 XT card when they are available and the price has normalized (hopefully middle of next year). I have checked Newegg for cards and all the cards I have looked at say they require an 850W power supply. As you can see from my sig, I have a 750W. I checked on Newegg's power supply calculator, and with all the components it let me put in, it said I only needed 471W (so maybe a 600W to allow for headroom). My question is, do I go with the recommended wattage and buy an 850W or do you guys think my 750 will be ok? I don't want to fry any other components by having a PSU that doesn't work with a new video card. Would 750W allow for overclocking (since Newegg thinks I only need 471W) even though the recommended is 850W?
