    Default New machine build - Green horn in the house - Help !!

    .
    .
    I am going to try to build a gaming machine but I am a green horn to this so your comments, good or bad are welcome and will be taken on board.

    My interest is in playing games like Shogun II, Skyrim and BF3.
    I want to build a machine with parts that will have at least a few years of future proofing.


    A few Questions for the forum:

    Q1. The Asrock website lists the graphic cards that their motherboards support in SLI/CrossFire configuration. For the Asrock Fatal1ty Z68 Pro, the Radeon HD 7950 is not in their support list.

    ASRock > Products > Fatal1ty Z68 Professional Gen3 > SLI / CF Support List

    The highest Radeon that they have in their support list for this fairly high end motherboard is the HD 6870.
    Do you think that Asrock have simply not updated their support list because they just haven't got around to it or might it be that the Asrock Fatal1ty Z68 Pro does not support a HD 7950 in a cross fire config. Maybe I need to go with an X79 mobo.


    Q2. What case would you recommend for this rig. My budget is about $200 + little more for a real good one.

    Q3. I welcome critical comments on the components selected for the rig.



    Main machine components selected so far:


    MOBO - Asrock Fatal1ty Z68 Pro Gen 3.0
    CPU - I5 2500K (I will overclock to 4.5GHZ)
    CPU cooler - Noctua NH D14
    RAM - G.Skill Ripjaws XF3 2 X 4GB (maybe 8GB is not enough)
    GPU - ASUS Radeon HD 7950 X 1 right now + another later in Crossfire
    HD - Patriot Wildfire 120GB Sata 3 (I will load the Operating System and some games onto this)
    PSU - Coolmaster Silient Pro 800W (Will this have enough juice to support all crossfire?)
    Case - Not selected yet
    I will use my existing hard drives and sound card which are both several years old.

    Thanks for all the advice in advance.
    Regards Billy...

    Your Coolmaster Silient Pro 800W has some issues that are not ideal for a highly overclocked Crossfire system:
    From Cooler Master Silent Pro Gold 800 W Power Supply Review | Hardware Secrets:
    Noise and ripple was always higher than we’d like to see in a supposedly high-end product. As you can see below, with the unit delivering 800 W, noise level at +12 V was around 95 mV. While still below the maximum allowed (120 mV), we always prefer to see power supplies presenting a noise level below half of the limit. The -12 V output failed to stay within proper range. During test one it was presenting a noise level of 108.2 mV, increasing to 120.6 mV on test two, 137.2 mV on test three, 119.2 mV on test four and 164.4 mV on test five. While this output is not as important as the others and is mainly used by some audio cards, we have to point out this flaw.
    and
    • Although supporting three video cards that require two auxiliary power connector each, video card connectors share the same cable instead of using individual cables, a problem not found in Corsair HX850W.
    • Corsair HX850W has 12 SATA power connectors and 12 peripheral power connectors. Cooler Master Silent Gold 800 W has nine and four, respectively.
    • Presence of some Taiwanese capacitors on the modular cabling printed circuit board instead of having absolutely all capacitors made in Japan, a problem not found in Corsair HX850W, where absolutely all caps are Japanese.
    • Noise level above specs at -12 V output. With Corsair HX850W this problem didn’t happen, however in our tests we found a high noise level at +5VSB output instead, but Corsair sent us their oscilloscope screenshots showing low noise level, and we had to assume that our equipment was misreading the results for some reason.
    • Although inside specs, noise level at +12 V was higher than we’d like to see in a high-end product.
    • You get 50 W more labeled power by buying this unit from Corsair.
    Your system should not require more than 80% of the power supply's rated power output (at elevated temperatures) for an extended period of time, such as when gaming.

    With an overclocked system and overclocked HD7950 Crossfire setup, even a top tier 800 watt power supply is probably barely adequate. A 900 - 1000 watt power supply is a better choice and you won't be stressing the power supply.

    If you do a lot of frequent gaming, buying an 80+ platinum rated power supply might save money in the long run over a 3 - 4 year time frame.

    Antec, Corsair, Enermax and Seasonic make some of the finest top tier power supplies.
    Recent power supplies made by SuperFlower are also excellent.

    Check out psu reviews from JonnyGury, HardwareSecrets, PCPER, HardOCP and/or TechPowerUp to find the best quality power supply that will meet your needs.
    Many name brand power supplies are mediocre at best.

    **edit**
    Check with ASRock and Asus tech support to see if they have tested HD 7950 models with your proposed motherboard.

    As far as the case goes, I love the HAF cases. I have the HAF 922 and there is oodles of room inside, but still not the biggest case they make. Nice if you are not looking for bling, real nice if you hate working in restricted space.
    Outside of that, pick one with enough inside/outside drive bays to suit your needs. Do you need eSata port on the front, front USB3, etc. You can always NOT use what is there but CAN'T use what is not there.

    My 2-cents for the case and I am biased because it has loads of space and fits my dual radiator on top just dandy

    I agree. RAM is real cheap right now and I just boosted mine to 16GB.
