go with the i5 3350p if your not overclocking, it costs like 30-40 dollars less than the i5 3570k but still offers great performance and also draws slightly less power, 69w max tdp for i5 3350p, 77w max tdp for i5 3570k, go with the asus p8z77m motherboard, cheaper but still good, and get the gskill sniper 8gb ddr1600 1.25v ram, this ram is supported by that motherboard and will work at its actual settings by default if the processor is kept stock too, instead of getting a 1tb mechanical hard drive which you dont need that much space really and also a samsung 830 ssd, just get one SSD for your main storage device and primary device for the computer, if you get both a ssd and mechanical drive, you will still have a noisy mechanical hard drive, i would rather get a ssd with a decent amount of space, preferably 256gb in my opinion is good for a few years if your downloading lots of stuff at a fast pace or all at once, dont waste your money on a 150 dollar computer case, go with the corsair carbide 200r, its a better choice, it will fit up to 300mm graphics cards with drive cage or longer ones without, and up to 160mm height coolers, which btw you should get one, the noctua nh-L12 is a good choice, for psu, 750w is good but the one you picked out is a little pricey and 750w isnt really needed, a good quality but cheap 650w psu would be better and could still handle really high end systems, the rosewill capstone 650w m is a good choice, and for gpu, i would rather get the gtx 660ti, i seem to found one for a lot cheaper on ebay, this card would be a better choice for 225 dollars, a lot cheaper than normal gtx 670's. make sure to use good thermal paste when putting it on your processor, the prolimatech pk3 1.5g is a good choice found on ebay for like 5 dollars, 21.5 inch led monitor with 1080p resolution is recommended, cheap but good wired keyboard and mouse, windows 7 64 bit operating systems, either home premium, pro, or ultimate.., and if you can, go with a wired internet connection. dont forget a cd rom if you dont have one, oh and for the computer case fans, keep them all at medium, good cooling but fairly quiet still, i dont know about the noctua fan if it even has a adjustment on it but even if its configured at high it should be still really quiet anyways here are links to most parts-
