Well my i7 @4.2 and a 5870 at stock pull 190watts idle with 5 case fans running, average around 280watts when the gpu is maxed out and 380 watts with both cpu and gpu maxed. Most games i play bfbc2, fsx etc pul the 290watts for most of the time. I only ever see it go above this when running benchmarks. These readings are all from my inline energy monitor which only measures the power going to my pc.
