You've done a pretty good job for your budget. Choosing Intel over AMD seems to be the far better choice now and into the foreseeable future. Nvidia's drivers coupled with EVGA's Precision control software are very competent right now. A 650W PSU is more than enough for your system (even with your system under full load - you would be very surprised). Maybe do what those guys said and see if you can squeeze out a little more cash for a 760, since you're going to be looking at a ~$50 difference there, with a significant increase in performance. Also maybe see if you can find a similar Western Digital drive instead of the Seagate, as WD drives are in my experience a bit more reliable and less prone to making a lot of unwanted noise.

Like a lot of people here I've been following Ryan Davis and most of his colleagues including all of the Giant Bomb guys since the days at Gamespot, and nearly religiously after Giant Bomb was founded. I have yet to even begin to process Ryan's passing and I can't even imagine how the rest of the staff is feeling at the moment, but I would like to say that if it's worth anything my heart goes out to his family and others that were close to him. Only following him through the website over the years, I can only begin to feel the loss that everyone who knew him personally is going through.
Ryan always displayed an uncanny knack for making guests feel comfortable, while at the same time displaying a resolve always to challenge the guest or take potshots at them all in good fun. He also possessed an unrivaled prudential awareness on camera when charged with handling weird live show hiccups and awkwardness. If he was hosting a show you got the feeling that, somehow, everything would work out okay no matter what. He was hilarious when he was upset, and hilarious when filled with glee. He had an air about him that was impossible to ignore - an innocent child-like enjoyment of things he found amusing - and when I watched him talk about video games I always felt at home, like I was part of the club. Ryan was truly a delight and will never be forgotten.
So here's to you buddy. I have always loved you and I will always love you. I will always remember you for being the awesome person that you were.
Rest in Bomb Squad Heaven,
Rest in Duder Heaven,
Rest In Peace.
Most systems, even with SLI or Crossfire setups, don't even use 600W, even under full load. You'd be surprised. Tom's Hardware has a bunch of charts about stuff they've tested. You should be completely fine with a 550W, assuming it's at least of "name brand" quality.
