I did a little shopping around, and these are the best prices at the moment. Then you gotta add a mobo.
Ideally I'd get the Asus Maximus 4 extreme gene z. If you're gonna get the 3570k (k stands for unlocked for overclocking) the M4E has superb overclocking ability and keeps your mobo and CPU safe, so you can get ideal overclocking by just running a program integrated with the mobo. I run my 2600k @ 4.5ghz stable using this program.
http://www.newegg.ca/Product/Product.asp...6813131806 @ 189.99, which would put you at 715$ with the SSD or ~700 with the HDD. Again I strongly recommend SSDs they make
everything faster.
For something a little more economical but still very good get the
http://www.newegg.ca/Product/Product.asp...6813157301 @104$ putting your total @ 629 SSD and 614 HDD. This mobo is also very good, features 1 PCIe lane 3.0 for next gen GPUs, and 2 additional 2.0 lanes. So you get the 6870 and if you want add another one. I use 2x 6870 and I get benchmarks that equal those of 580 for 2/3 the price.
Maybe try seeing if your old HDD works and then getting the SSD.
