Alright, here are some tips on what I would buy with a budget of approximately that:
CPU - Intel Core i7 2600k (Make sure it has a k in the model, Means it has unlocked multiplier and you can Overclock it in future)
CPU Cooler - Thermaltake Frio
RAM - 8Gb G-Skill Ripjaws PC3-12800 CL7
Motherboard - Asus P8P67 PRO B3
Graphic Card - Sapphire HD6970 2Gb
HDD - Western Digital Caviar Black 750Gb/1TB (Whatever you want, 750Gb or 1TB, also if you want an SSD, you can add a Vertex 2 60Gb for your Windows 7 and programs, or a Vertex 2 120Gb).
PSU - Corsair HX750
Case - It's up to your likings to be honest, I could recommend many, like a Cooler Master 690 II Advanced, a Silverstone Raven RV02B-EW... etc
Now, I don't think I am missing anything, let me know if you need more help!
