  1. If it has "K" at the end then it can be overclocked in the right motherboard if not it can't.
  2. Best answer
    The non-K series are what Intel calls "Partially Unlocked" since Sandy Bridge. You get 4 bins (1 bin is 100 Mhz, or whatever the base BCLK is set to, in this case) on top of the max turbo clock. So the max you will be able to do with the 4771 is 3.9 Ghz (max turbo) + 400 Mhz (partially unlocked multipliers) = 4.3 Ghz max. With a small bit of BCLK adjustment, you can get 4.4 Ghz (most likely stable).

    If you are bent on OC'ing more than 4.3 - 4.4 Ghz, you have no choice but to get a K-model (and a good cooler). Otherwise, you can get away with a 4771 just fine. However, the price difference is nearly nil between the two models, and they both Turbo to 3.9 Ghz, so there really isn't much of a difference. If your priorities with a computer is as you listed, you won't miss any of the pro features on the non-K models (that's right, the K models lack certain features like Trusted Execution). If the price is nearly identical (within 20 bucks in my opinion), go for a K model would be my suggestion.

    Most motherboards offer some form of "Turbo Enhancement" where all the cores are working at the max Turbo speed, not just 1 or 2. So you can usually count on the 4.3 Ghz as your all core max speed.

    As for system limits, usually you get plenty of warning signs before something goes seriously wrong, such as crashes, and unusually high temperatures (on the CPU or the VRM on the motherboard). You can always establish a good baseline by reading a review or two on your preferred motherboard, to see what the reviewers have said about the OC capability of that board. Most of these boards also come with a tuning utility (in the BIOS/UEFI or in windows) that allows you to essentially push a button/click once to automatically overclock, which is great for beginners. That option is very safe and usually takes you to with in 15% of the max your CPU+Board+Heatsink/Fan solution is able to do, and that's typically enough, unless you plan on beating records.

    is MSI Z87 MPower Max better thean Asus Z87-PRO ATX LGA1150 Motherboard
  8. Not really, the Asus has all the features that a good board needs inclusive of enough power phases for overclocking.

    can you comment on MSI Z87-GD65 GAMING vs asus Rampage IV Extreme Motherboard vs
    MSI Z87 MPower Extreme vs Asus Z87-PRO ATX LGA1150 Motherboard
  10. The PRO and the MSI GD65 are in the price range I would be looking at but here is a couple of other Asus boards and I would actually consider the Hero http://www.newegg.com/Product/Product.aspx?Item=N82E16813131989 http://www.newegg.com/Product/Product.aspx?Item=N82E16813131976 Spending over $200 gives diminishing returns since the performance of the boards around that price has already reached top level.

    I am very happy with my new rig. Im getting 4.3 stable, but used to get 4422 before I stopped using Asus Suite. Now I just use the Bios.
