System Builder Marathon, Q1 2014: The $2400 People’s Choice PC

Results: Grid 2 And Arma 3

Performance in Grid 2 scales opposite of Battlefield 4, favoring the GeForce GTX 780-based machine in six out of eight tests, and switching over to last quarter's configuration at the highest two settings. That box with the Radeon R9 290s in it appeared more processor-bound though, and we've noticed similar CPU-dependencies from AMD graphics cards in the past.

The current build’s GeForce GTX 780 cards in SLI make a clean sweep of Arma 3, contributing to an overall gaming lead of approximately 12%. Can the older machine and its hexa-core processor catch back up in the rest of our benchmark set, though?

    It's not calculated power, it's measured power for the entire system (at the power plug). No addition or subtraction was used.

    1.) Start the system, wait for all processes to load, take a measurement (Active, but idle)
    2.) Load the CPU using eight thread of AVX-optimized Prime95, take a reading (CPU Load).
    3.) Load GPUs with 3DMark 11 Test 1 in loop, take max reading as it heats up (GPU Load).
    4.) Load both applications (CPU+GPU Load).

    The "math problem" is that any program used to fully load the GPU also partly loads the CPU. So when test 4 is Prime95+3DMark, Prime95 can only use whatever CPU resources are left with 3DMark running.

    So the most accurate system power reading is with "CPU+GPU Load" applied. The system measurement for "CPU Load" still includes the power of an idle GPU. And the system power measurement for "GPU Load" still includes the amount of CPU energy it takes to run the GPU's test application.

    Interesting move, showing the nicest build 1st instead of last. Cant wait to see all the builds compared and see what you all come up with as the budget goes down.

    Looks good. Surprised only went with a 750w PSU though. Considering 2x 780 ti's and overlocking

    Yessir, two 780s and a bit of experience in part picking lead me to expect around 700W of required system power. And, it came out just a little less than 700W.

    Power supplies of greater capacity and similar reliability at this price tend to be lower-efficiency units. And we like efficiency too.

    Very much appreciated and satisfying answer.
    Thanks Crashman :)

    Any chance of including these calculations in all future articles, so that we know exactly how the power graph is calculated? Ta.

    wow. such performance. many ram. they should've put in 16gb of ram for real high-end specs. ;)

    As I'm into quiet enclosures, I'd go along this route:

    Wondering how much of a difference would non-reference cards make. Obviously, CPU cooler and RAM could be different, BR drive optional, storage drive as well.

    Shouldn't that be DDR3-1866?

    Nice comparisons to last quarter's build. All things considered, I think this is the best build I've seen in this series for quite a while.

    I like the new focus and high end review first. This build mirrors my own approach except I don't play games so save on multi-GPU costs and no need to water cool as no overclocking either – stability is key to me. My similarly parted machine in November less the water cooling and multi-GPU cost almost $800-900 less after rebates. Can you add sound/noise dB monitoring and include in results? Multimedia machines and home office machines need to account for noise.

    Note: Arma 3 is largely CPU bound, and seems to favour IPC.

    I enjoyed the article very much, and I appreciate the new direction you're going in for gaming value. However, you don't need to mention that the prices of the 290 spiked last year. Seriously, we get it and you only need to say it once or twice instead of seven or so. Aside from that, still a very informative and well-thought out article

    When can we expect to see Tom's switch over to 4K gaming benchmarks? This build should be able to handle it and I want to keep tabs on both hardware and driver updates.Furthermore I think it is safe to say an enthusiast that is going to buy a multi-monitor setup probably already has one, but there are probably other like me that are waiting for reasonably priced hardware to be capable of handling 4K before buying a new monitor. Even though I haven't seen a 4K monitor that preforms like a "next Gen" technology should.Also now that Tom's has been very though covering multi-monitor resolutions I understand (and I hope other readers do as well) how they typically scale.I don't want to be a jerk I'm just trying to ask for an ETA, and if I don't ask, how will you know what I want?

    2400$ and hdd... pls
    my fix is get a 700gb ssd, 780ti no sli problems, and a i5 4670, this is a much better gaming pc, and can go quiet build.

    ^ An i5 with a 780 Ti? Come on you are asking to be bottle-necked! I bet you were one of the people that kept advocating a Pentium + 660 a couple years ago when people mistakenly thought dual cores would be the standard forever...
