ivy bridge performs better than sandy bridge and uses less power. a 4ghz ivy bridge would be the same as a 4.4ghz sandy bridge given a 10% increase clock for clock performance. heat problems dont exsist until you hit 4.5ghz which you shouldnt anyways
i got a 670 with a better cooler and a higher overclock from the box. the gpu is also specailly binned for more OC
crucial is just so much better than corsair force gt
That build looks really good but I'd switch out your primary SSD with a Crucial M4 and I don't think the exhauster is needed. Your case includes an exhaust fan so you're basically buying the same part twice.
I will consider about 3770k and ASUS GTX 670. I took the v6 instead of Hyper212 cause it is not that unusual an ambient temp of 30-40C. I cannot depend on air conditioner. That said, would u still recommend the Hyper212 (it is cheaper, of course)?
About the HD, I really need the 2Tb.
PSU and RAM: You really do not like corsair hehehe. I will search some reviews about these brands. But do u think 750w is really necessary? I thought 650w was even too much.
OFFTOPIC: Brazillian taxes are some of the highest in the entire world. The system uses what we call "cascade" taxes (taxes over taxes over taxes). Much corruption, I fear. Technology is one of the most overtaxed areas. A computer game or video game is taxed at 70-100% rate when you import, it is taxed as a "gambling game", just like a slot machine. And saddly I am not kidding. If you think 60 bucks is expensive for a blockbuster, try paying $120 for the same game. Now use the Real(BRS): ~R$240-300 (depending on store and game). For each dollar you earn in a certain job, here we earn 1 real (something like that). In other words, we pay something like 4 times you pay for the same game. Where are my Fork and Molotov?
