I think everyone has said it but go with the i5 2500k, you do not need hyper threading for gaming and it is a small performance up to 2600k with a huge gap in price. Also, 16 bg of Ram? That is a ton...usually only need 4gb for gaming unless you plan on hosting servers and such. I say go with a 650w powersupply, http://www.newegg.com/Product/Produc...82E16817139012. Also you are spending way to much on that cpu cooler. I say go for a hyper 212+ http://www.newegg.com/Product/Produc...82E16835103065. Also for the case, I would find one that has more fans and a little cheaper if you want to add more to your gpu or whatever.For the MOBO unless you plan on doing intense video editing oc then that price of MOBO is unnecessary. Go with p67 pro or asrock.
Hope this helps.
Well i forgot to say i live in Japan , and the prices here are so cheap the difference between 2600k and 2500k are 40 USD (At least where i buy pc parts)
on this computer build im gonna spend 1800 USD , usually its too much for an computer? on my first computer build i spent 1500 USD.
Im not bragging my self but the money its not the main issue.
