Have an aging but respectable Q9650 - will be OCing it. Upgrading my youngsters gaming PC. Adding an SSD and video card, Ocing the CPU upgrading CPU cooler. (If I wanted to spend several hundred more I could get another system etc, but not interested right now.) I'm interested in pushing the 775 system as hard as I can on a budget of $200 video card. If I burn something up..well time to build a new one with an OC'd i5 or something...till then. These seem like the best contenders for the price. Suggestions? Have a 500W PSU Bronze - I hear Radeon can draw a bit hard on 500w systems...should I be concerned? Thanks if advance.
