Power, Heat, And Efficiency

System Builder Marathon, March 2011: $2000 Bonus Build
By

More powerful graphics cards hurt the new build’s power consumption numbers, but only when 3D applications are running. Fortunately, we also know they increase performance. So, the efficiency charts should reflect those two figures balancing each other out. These charts only reflect one half of that equation.

CPU temperatures are excellent for both systems. Because GPU overclocking required manual fan adjustments, the numbers are not comparable in a precise manner.

The new build outperforms the original in games, but nowhere else. The former build actually beats it slightly in overall performance.

We reduced the effect of hard drive performance on overall performance scores from our previous 25% to the current 10%, since most people spend no more than 10% of their work time waiting for programs to load. Our three non-gaming application suites account for 30% each of today’s total performance score.

Small graphics performance gains that usually occur only at our highest test settings were more than offset by increased power consumption in our efficiency charts, allowing the original build to take a big lead.

    I originally joined Toms Hardware Shed to post on the forum, looking for someone to help me with the new i7 technology and find a perfect system.

    I posted in the Forum, I didn't get any replies. I think now I see why this was.

    Everything I need is here! This is a great article / guide, it's informative and precise, it answers my questions on a technical level I "just about" understand. Your component choice and explanation to why your using each choice is also very insightful and useful!

    One of the area's I'm now trying to explore which is quite new to me is SDD's. I notice in this set up your using a SATA Drive and 2 x SDD's.

    (I haven't read last months post yet, which I will now) If my query isn't addressed there, can you please tell me;

    What are your reasons behind having 2 x SSD drives rather than 1 larger drive i.e. a 96GB or 128GB Drive from Kingston which would cost around the same money as you've spent.

    OR

    Why have you not suggested alternatives like a Hybrid Drive (SSD/SATA) like the "Seagate 250GB Momentus XT 2.5" Hybrid HDD/SSD - SATA-II 7200rpm 32MB Cache - OEM" which I've researched and noticed exceptional speeds (VERY close to SSD Speeds) yet are much cheaper.

    Anyway, thank you for the post, your site has been my bible these last few days and I'm rekindling my love for this stuff! Each post leads me wanting to read the next!

    I look forward to your answer eagerly, kind regards, John

    P.S. Can you direct me to recent "Sandy Bridge" Silent PC build or suggest way's I can almost silence a build like this?

    My CPU heatsink and Memory are already installed it doesn't matter, I'm using the stock HeatSink at present so in an ideal world if there's no post's you can direct me to, can I ask;

    What would be a good way to silence this build...How can I reduce the noise?

    Would it be:

    PSU
    Hard Drives
    CPU Fan
    OR
    Chassis Fans

    making the most noise in this build at this point?

    I'm asking this as my next purchase "ASAP" is going to be Case, I wanted something a little sexier than the case you've chosen but something also "very quiet"...

    So am I wasting my time looking, should I be instead thinking of water cooling, a Zalman Solution or another area of the build like the PSU?

    I'd like to mention that I understand I'll need to pay more to achieve this, I am willing to add more funds but would still like to be realistic and economical.

    Many Thanks!!

    John
