System Builder Marathon, March 2011: $2000 Bonus Build

Power, Heat, And Efficiency

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.

    Great build! Can't wait to see what is in store for next quarter!

  • Great SBM series. What about an AMD quad core vs. an AMD triple core (unlocked 4th core) vs. Core i3 value comparison?

    Now this is pretty interesting. I wouldn't have suspected that the memory bandwidth reduction in the alternate build would have been as big of deal as it is. I think both builds are fantastic, but the NF200-equiped Asus board was one I myself was trying to obtain. It has been deactivated on the Egg, and the winner of the original $2000 build will be extra lucky indeed. Hopefully, it's me.

    Now when you win the second PC, there will be no need for sadness: You can upgrade it with the motherboard from the first!

    I'd love to see more info on 16x/16x vs 8x/8x. I just looked at the last time you guys reviewed it, but it was only with a GTX480. Being one of many with a P55 8x/8x mobo, I really need to know what my best upgrade path would be... single top end card at 16x? Or CF/SLI again? Is the resolution going to be the deciding factor? Seems like high res sees less of a PCIe bottleneck at 8x, but maybe it's just due to framerates being lower? Need info! lol.

    This is why the SBM is the best thing going. A few other sites do similar articles, but Tom's is far and away the champion. Another well respected site doesn't even build the systems, but Tom's builds three (or four!) and gives 'em away like sweet delicious candy. Every build has its's own quirks, issues, and performance wins (losses too) that can't always be understood until the gear arrives and goes together. If system building was entirely predictable, no one would build their own. It's just more fun this way.

    antec 300 again... im really not liking that case. you have any experience with the haf 912? it seems like a very nice case.

    Anyway, i never understood why intel went with just 16 lanes on SB yet all the mobo makers market their ultra high end cross fire boards. :pt1cable:
    Thing I'm wondering is, if intel switched to 24 lanes, could the graphics cards work at 12x each for 2 way, and 8x for 3 way? i know a full 32 lanes is unlikely, that's why I'm asking.
