System Builder Marathon, Sept. '09: $650 Gaming PC

CPU And Cooler

Processor: AMD Phenom II X2 550 Black Edition

The original intent was to squeeze a Phenom II X3 processor into this month’s budget machine, but in the end, it just wasn’t a possibility. The $100 Phenom II X3 710 we used in a recent overclocking article was out of stock and the $120 Phenom II X3 720 Black Edition pushed us just outside the flexibility of our budget.

Instead, we opted for the AMD Phenom II X2 550 Black Edition which has seen serious street pricing fluctuations since its release. This Phenom II has two functioning cores, runs at 3.1 GHz, and has 6MB L3 cache. It won’t offer the same performance as a triple-core in many of our multi-threaded applications, but with higher stock core speeds, should put up some higher numbers in the single- and dual-threaded tests. Further, it provides solid overclocking potential and, if you are lucky, even has the potential to successfully unlock the disabled cores. 

CPU Cooler: AMD Boxed Cooler

The first sacrifice we made in the interest of cramming all of these goodies into a $650 budget was utilizing the “free” bundled AMD cooler. The all-aluminum heatsink is identical to the one on our Phenom II X3 710, and has nowhere near the cooling potential as the copper-base and heat pipes found on the upper quad-core Phenom IIs. A 70mm x 15mm fan covers most of the aluminum, making this cooler look downright puny compared to one of the 92mm or 120mm aftermarket coolers we would like to have used. We may not be able to push CPU voltage far with this cooler, but the dual-core Phenom II still has the potential to reach 3.5 GHz at stock voltage.

    A nicely done build, great work with overclocking on a stock cooler and an impeccable write up. Thanks for the great article Mr. Henningsen. AMD did a good job for a budget build, especially at stock clocks.

    Great article! It's crazy to see all of that packed into a case for only ~$650.

  • I usually love reading these, but this time I just went directly to the comment section. There's no point in building or owning an amd box, they are too weak compared to modern Intel/Nvidia based systems.

    Wonderful. =D

    What about the new $100 quad core athlon with no L3?
    I know I like extra cores. Wonderful choice regardless.

    I wonder what the quad core athlon with a 512MB 5850 (which would increase the budget though) will be like. Both cheap yet highend parts. =D

    Nice to see what only a pocketful of cash can get you.

    i know it wasn't available at the time but what about that 100 dollar quad core the athlon II x4?

    Good article. I know you stated you were leaving the "unlocking" of the other cores to the winner of the contest, but were you guys able to unlock? If so, could you re-run those benchmarks? Again great article.

    While "forcing" all AMD builds for a single marathon is a good idea, the timing is somewhat unfortunate.
    An article which explores the performance and value of a complete Lynnfield build is something I (and many others, i'd dare to guess) would like to see but haven't yet, and this month's SBM is a missed opportunity in that regard.

    That's a bitchin budget gamer system especially looking at the gaming benchmarks.Just this month I was thinking about building a similar type of system with the Phenom II X2 550BE.I was going to go with gigabytes 785G type board (just one graphics card slot) though however I may reconsider that especially with what you presented here although I was shooting for a much cheaper budget build (about $180 less than what you have),Newegg did have a gigabyte 785G board with the Phenom II X2 and $20 off in a combo deal until the end of this month.
    I think that your choices were better than mine (more powerful).

    Another alternate mobo - 785G ...they are availbale in AM3/AM2+ flavours and have SB 710, which can allow core unlocking -http://www.newegg.com/Product/Product.aspx?Item=N82E16813128394
    But not sure about their o/c potential though...

    Nice to see a cheap system still using a quality motherboard.
