System Builder Marathon Q2 2015: $1600 Gaming PC

How We Test

Test Setup

I covered some of the points on how we tested Big Build in the prior Overclocking section. Aside from those notes, we purchased the parts, assembled the machines and ran the tests ourselves. I set up Big Build and the other machine in our Los Angeles test lab where I had access to the tools and space needed for this quarter’s System Builders Marathon. One key factor that I find important for working in the lab is having a climate-controlled environment to run the machines in, especially when testing the overclocking. Since most of my work was done at night, I had the A/C to myself and set the temperature to about 73 degrees F. With both machines fired up around mid-afternoon, the room's temperature rose to about 78 degrees F.

Using the standard Tom’s Hardware image and software, I benchmarked the non-overclocked PC configuration first, then set the overclocking on that machine and ran the tests one more time.

The 27” Viewsonic VP2780-4K and 28” Acer XB280HK let us test in style and convenience thanks to Nvidia’s Surround setting.

Aside from the variety of tools and hardware needed, we also introduced 4K monitors to the test scenario. We used a couple of 27” Viewsonic VP2780-4K displays sandwiching a 28” Acer XB280HK. Since Big Build’s Gigabyte GTX 980 graphics card had three DisplayPort outputs, we used them all for testing.

The images we use center on Windows 8 and are pre-loaded with all of the System Builder Marathon software. We simply write a fresh image to the machine's SSD, update the firmware, install the drivers and configure third-party tuning apps.

    your listing for the GTX 980 in the article links to the motherboard.

    i like that the builds finally contain both ssd and hdd as well as some alternative cooling solutions this time around. nice to see that there are other options for cooling besides the normal suggestions that still do a nice job. that case also seemed like a decent choice though for the money, i'm sure there are better ones you could have gotten.

    now cue the corsair psu haters in 3....2.....

    edit: i see a lot of different ideas of what "could" have been done with the money, but honestly we all know what these suggested parts can do already. using non-traditional parts in the build gives up numbers on some pieces we may not have tried out before. the numbers may not be overly positive but i learn something from them either way. so maybe take this as a lesson on "what not to do" and move on if you're so inclined. always nice to see stats on machines built with "other" parts at least for the learning opportunity :)

    Is there a typo with the price on the gtx 980 or did you pay more for it when you got the components? I'm showing that the price of the system (minus Windows and not counting in shipping) of ~$1295 (a little over $200 shy of the $1600 mark).

    There is a LOT of waste in this build. You can get the same build, with all the same specs, while paying $300 less.

    You can get RAM for almost half that price, a good SSD for about half that price, and an SLI-capable motherboard for half that price.

    According to tom's own benchmarks, RAM doesn't have a significant impact on performance in gaming, any reason why the gaming PC is featuring memory overcosted by about $50-$60?

    There are some major typos and incorrect links here. Somehow I doubt the GTX980 price of $169.99...
    If it is I want one!

    Wow they were only getting to 4.2GHz at 1.24v and hitting 89C+ on three of the four cores. That is not good. Not sure if it's a bad chip, but even that mid-range cooler should do way better than that. For comparison with my 4690K on a Noctua NH-D14, in the summer I scale back my overclock and run at 4.3GHz at 1.12v and hit mid-50C even with a 78F indoor A/C setting.

    A lot of waste, 8 gb of ram and a cheaper case would of put you just shy of the gtx 980ti price range.

    You can get an Intel Xeon E3-1231v3 for $7 more on newegg: http://goo.gl/qlzkrA

    I am not a gamer but I do build a lot of CAD workstations at work. I do not see why the xeon is not a massive improvement over the i5. It is missing the integrated graphics, but that should not matter for gamers same as it works for my CAD workstations.

    I have wondered about this for a long time, someone please explain.

    Was it possible to mount a case fan on the other side of the Zalman cooler, or did I miss something? If it was, then you could have gotten the temps down by a few degrees in a push-pull configuration.
