Hello, I am planning to build my own computer soon and I want to purchase the ASUS ROG Maximus V Formula when it releases. Since it is a Z77 Chipset, should I get an Ivy Bridge in order to utilize thee PCIE 3.0 on it, or run for a I7 2600k. I don't like how the 3770k runs hotter than sandy bridges, but im not too sure. What should i get?
Country: I Live in the US, NY to be exact.
Tasks: I plan on overclocking(obviously). I am a hardcore gamer,which is what I plan to builda computer optimized for.
Budget: Doesn't really matter since the difference between both CPU's isn't huge
Get the 3770K. Yes, it runs hotter but this is only to be expected. Its smaller size means less surface area to expel the heat. It still performs slightly better than 2600k, both at stock and overclocked. To be sure the difference is so slight that you will never notice it, but the 2600k is now obsolete and the 3770k is its replacement, and there is really no reason to get the older chip.
PCIe 3.0 is not a reason to get it though. PCI 2.0 already gives you more bandwidth than you will ever need.
One last thing, if games are your thing, then a better choice would be the i5 3750K. It's not better than the i7 3770K but it's much cheaper and no worse. The i7 is worth it if you do a lot of video editing, modelling or simulation work.
There is a nice piece up on the 3rd generation Intel® Core™ i7-3770K and overclocking with it on the front page of Tomshardware. In the end because of improvements to IPC on the 3rd gen processor even running at a lower speed it ends up being about equal in performance with the 2nd generation Intel Core i7-2600K. So the real question comes down to if you are going to take advantage of PCI-E 3.0 at all? Since you selected the GTX 680 which is about the only card that is really tapping into the PCI-E 3.0 bandwidth it sounds like you should go with 3rd generation Intel Core i7-3770K.
