I'm in folding 24/7 with a Radeon HD 7870 (7930) and Core i5-3570K with the folding slider all the way to the right, does having the screensaver enabled or disabled give me more PPD? Thnx. PS: how many watts do you think this will eat up? I have a Kill-A-Watt but I can't plug it in because there's no space on the power stripe, and I also have no idea where I put the KAW. 500W 80Plus Gold PSU.
