Hi Salmo,
Your proposed rig looks great, including that hefty 3-Gig GTX580 card. The only thing I could point to is the 650 watt Corsair PSU. it should be adequate for the rig you're putting together, but may become a limiting factor for future hardware upgrades or additions. For relatively little extra cost you may wish to consider a 850 watt unit or better. However, that is not a deal breaker by any means -- I'm green with envy over the setup you've listed. Good luck!
