System Builder Marathon, Q4 2012: System Value Compared

Value Conclusion

We’ve determined through trial and error that the best bang for the buck, when it comes to building your own PC, is usually around $800. Any less and you're leaving performance on the table. Any more and you're subject to diminishing returns from higher-end components. Our $500 PC builder, Paul, almost always expects to lose the value comparison to Don's $1,000 build, and vice versa. 

Today, Paul's machine sets our baseline, and is exceeded by Don's. Yes, as we saw on the previous page, the FX-8350 is less efficient. However, when you factor power out and look only at performance per dollar, this quarter's $1,000 configuration rises to the top in its stock form and even more so after overclocking.

Productivity applications prove to be the $1,000 machine’s forte, adding street cred to its Piledriver-based AMD FX-8350. The $2,000 machine clearly outpaces it everywhere, but not by enough to justify its far higher price.

We’ve grown accustomed to the $2,000 machine being on the wrong end of the performance-cost curve, so I’m happy whenever I see my finished product push an average value score over 80%. On the other hand, a few overclocking enhancements might have gotten it a few percent higher still.

But poor overclocking isn't the expensive build's biggest problem. Built for gaming, its lowest three test resolutions are all capped by Battlefield 3's 200 FPS limit. Worse still, the performance of its Radeon HD 7970 CrossFire array drops off in the same game at 2560x1600. As a result, anticipated performance wins of 50% at stock speed and 100% when overclocked drop to 34% and 51%, respectively.

The second chart completes Don Woligroski's win, and should put a smile on the face of anyone hoping for a tighter competition in the desktop processor space.

    actually the piledriver based build is more all-rounded, it can be a decent workstation and a decent gaming desktop for those who have tight budget

    Which of these builds is the most future-proof ?

    The piledriver build should have had some parts swapped out for cheaper ones to reflect the changes in pricing changes from last Quarter. That would have been a more fair comparison to the $1000 build from last quarter.

    For the $500 build, why would it have 60% of its value calculated by apps, when it was build for gaming purpose ?
    Just a thought, but shouldnt the percentwise distribution of value for each built based on the purpose for which it was built ?
    Something like : games, apps, storage.

    $500 build : 80%, 15%, 5% (cheapest best gaming with lots of cheap storage. )
    $1000 build : 50%, 40%, 10% (slightly better games over apps. Great apps. fast storage for boot)
    $2000 build. : 42.5%, 42.5%, 15% (equally good games and apps. fast storage should be plenty and fast)

    wow its unbelievable to see a $500 gaming pc achieve 50+ fps in Battlefield 3 at 1080p on ultra settings.
    goes to show how even a $500 pc can thrash and destroy xbox 360 and ps3.

    I was pleasantly surprised how well it turned out. I believe I would have gone with one that had less cores and spent the money elsewhere. Overall though, it turned out to be a pretty good machine. Now only if they could get the power usage under control.

    You need to use a slightly more complicated performance comparison algorithm. Something that takes into account the fact that over 120fps is useless and doesn't run into problems with things like fps caps at low res.

    Yeah the AMD 7850 really pulled its gaming performance up. Very nice too that the Intel G850 didn't choke it off. A sweet build!

    Um i must ask this, BF3, 2560x1600, ultra: is cross-fire not working? Why should 2 7970s serve up the same performance as a single 670? Or am i missing something? Thomas mentions the drop being "extreme" in his build's article but...something's wrong, i think...

  • So we're left with the AMD platform winning out the value comparison for no other reason than the mid-range Intel solution was not permitted to compete - so without filling all the places at the table this test is meaningless. The AMD solution only gets a default win due to no other permitted competition in that price range. This is garbage.

    Firstly, the bulk of sane consumers with even half a clue and with $1000 in their pocket would not have given the AMD platform a 2nd look if given the choice. Are we really suggesting that they would have thrown $1000 at a solution that would not give them a 3770K upgrade option later on if they felt like it?

    Also, this comparison deliberately factored out power consumption, which was rather convenient for AMD. I'm afraid you can't factor this out in this day and age, just because it's hard to quantify the cost across the entire globe. What you could do is produce some sythetics that represent average consumption over a given task and mutliply it up to get the total power over a year - then folk can work out what that would cost them in their own location. What I would like to know is how much that AMD solution would cost me to run for a couple of years when compared to a comparible Intel solution, and then work out what I could have bought with the money saved - it might not be much but I think it's valid - it could be the difference between a decent cooler or a piece of trash.

    Please make these value comparisons tell the whole story by including both platforms within that price bracket - I know that makes life hard for the reviewing team but boo hoo hoo, you're the ones that set out to prove a point, so do a full job please. Tell us the full story, not half of it.
