You could do better than that. You only need 8GB RAM for gaming. The psu is also overkill. I recommend Seasonic S12II 620 instead http://www.newegg.com/Product/Product.aspx?Item=N82E168.... Save a couple bucks on those and you could probably get a Radeon HD7950 as well. For $1k, you could probably get an SSD as well
Don't know if you plan to overclock but I put it in the build. If not, you can save with the non-K 3570, drop the cooler and get an H77 motherboard. Left the case off the budget so your looking at around ~$1050 with your case.
