System Builder Marathon, March 2011: Value Compared

Performance Scaling And Efficiency

The four real-world performance simulations from our hard drive charts were used to gauge storage performance. All other tests are an average of their respective suites.

Putting aside the astronomical performance differences between SSDs in RAID 0 and a single mechanical HDD, the $2000 PC has barely more than twice the performance of the $500 PC. That puts both it and the $1000 machine in jeopardy of a huge loss in terms of value.

Because most people spend only a small part of their time waiting for files to load, HDD performance represents only 10% of the total performance we used to determine efficiency. The combined performance value is still easy to calculate, since the other 90% is divided across three other suites (gaming, encoding and productivity) at 30% each. The formula would be written (3g + 3e + 3p + s) / 10, where g, e, p, and s represent the gaming, encoding, productivity, and storage averages shown in the chart above.

Even when it only represents 10% of overall performance, drive performance pushes the $2000 PC to 2.7 times the $500 PC's baseline and 3.4 times that same figure when overclocked. Even a pair of graphics cards couldn’t prevent a PC with that much performance advantage from conquering the efficiency chart.

    A $500 build, together with a Sony FW900 or equivalent monitor, could be had for under $800 total. Wow!

    Did you just say "$300 monitor on a $500 box"? Really?

    how much is a good surround sound system?
    how much is a blu-ray player?
    I rest my case.

    What if you scaled down from 100% as opposed to up from 100%? If the 2kOC machine had 100 in each category, the SSD would be "naturally" toned down. The $500 machine would be at ~40% for gaming, A/V and productivity, and ~10% for storage.

    Taking a simple average you'd get that the $500 machine is typically about 30% the speed of the $2000 OC machine. An SSD does improve the day-to-day performance of a computer significantly.

    Being the poor college student I am, the blue bar is my favorite. And that O/C'd $1000 build is looking pretty good in my book. I've built AMD systems since the Athlon XP days because the price/performance ratio of Intel chips just wasn't worth it to me. But, I shall have to take a close look at the Intel i5 for my next build.

    qwertymac93how much is a good surround sound system?how much is a blu-ray player?I rest my case.1) Surround sound system = not worth it.
    2) Blu-ray player = Definitely not worth it.
    3) $300 monitor = not worth it.

    Of course, this could be the my inner poor college student talking. I'm sure for some people it is worth it.

    you can get good LED monitor of decent size in under $100 and that would be perfect for $500 build.

    A job well done Tom! Thankyou.
    The $500 AMD machine underperformed in the CPU department. I think the Intel i3 2120 paired with a H61 motherboard would have been the better choice.
    $1,000 rig was near perfection.
    $2,000 rig suffered from CPU bottlenecks at resolutions lower than 2560x1600 so it should be paired with at least $600 worth of display(s).

    Well I think we are all thinking the same thing and that is holy jebus SSDs are awesome. 60GB SSDs are at around $120 now so maybe in a year the $500 builds will get an SSD.

    Your second to last paragraph needlessly bashes the $500 system. So a cheap build is bad for a user that only wants performance? Well, duh.

    Your $500 build was titled as a gaming PC and now that only counts for 30% of average performance. Mixing all of the stats into one performance bar is useless to everyone. Keep the gamer/av/production separate as that is more useful.

    If you wanted to alter these PCs from "Gamers Rig" to "Programmers Rig" (ie. capable of running several virtual machines, with Ubuntu 64 as host). What would you alter?

    I was thinking of taking the $2K model and
    -- doubling up the RAM from 8 to 16
    -- cutting from 2 SSD to 1
    -- downgrading the graphics card, to I don't know what
    -- deleting the CPU cooler.. I will not be over-clocking
    -- leaving the rest as is

    I propose downgrading the 2K PC vice upgrading the 1K because I feel ASUS/INTEL/Ubuntu64 combo is better for virtualization than AROCK/INTEL.

    Maybe the 1K PC can do it also.

    In the conclusion:
    the $2000 machines twin SSDs
