The new system price offer also seems high to me, considering there are no drives included and the other parts are mid-grade solutions. If you're confident about the condition of the used parts, you could likely get better components and/or save money doing the rest yourself. Power supply requirements for the 570 may not be as high as the box indicates. A decent 500W PSU should be adequate. Decent being the key word there. If you have an off-brand unit with a 20A +12V rail or some such non-sense then you'll need an upgrade. Otherwise you should be fine.
