System Builder Marathon, May '09: $2,500 Performance PC

Conclusion

Today’s $2,500 system certainly feels like a performance machine, but we’ll have to wait until Thursday to see where it stands against the less expensive builds of this month’s marathon. However, we can consider the impact of overclocking on performance and efficiency.

While the graphics system had the highest overclock as a percent of base speed, the greatest performance yield came in A/V encoding by way of CPU overclocking.

But overclocking increases heat and a warm system is usually less power-efficient than a cool one. So how much did overclocking hurt efficiency?

We’re thrilled to see an efficiency increase of 1% (actually, 0.6% rounded up) through overclocking in the chart above, and the added efficiency makes some sense because of the low voltage levels used to reach those higher clock speeds.

While supply issues led us to use substitute parts, identical specifications helped ensure that the substitutes had no performance impact on today’s build. And while the end product doesn’t look identical to the system we planned, it was still a pleasure to use.

Ed.: Stay tuned for part two of our System Builder Marathon tomorrow. And as mentioned, keep an eye out for the upcoming contest, where we give this machine (plus the other two) away!

    What's with the efficiency adage at the end i mean i get why but I'm sure most of us noticed that overclocking gave us more performance but at the price of a higher electric bill, but we'll do it anyways. :)

    Case is nice but i mean with such a high end system seems like a waste so cluttered yet it all fits which makes it pretty cool esp if you put it right on top next to your monitor makes a nice look factor but it's not my style though. ;)

    I'm sure the rest of the readers will be happy to learn you guys won't be interested in winning it :)

    Asus Rampage Gene > DFI Lanparty

    Antec Mini P180 would have had better airflow as well. It can fit even a 120mm fan and heatsink for the CPU, you don't have a PSU blocking it and adding heat to the air around the CPU.

    Very interesting as I have a pretty powerful core i7 matx build as well, however, here is what I would have changed if I were you:
    Case: Antec Mini p180 - much more room, especially if you remove bottom hard drive cage, can take ANY graphics then, much better cooling, and allows for REAL cpu cooler.
    Motherboard: Asus Rampage II Gene - I used the DFI model then got the ASUS, its nicer, much nicer. Unless you need a couple specific overclocking things in BIOS, id recommend Asus board hands down, AND it has 2 firewire, one header, and one rear.

    For those that care (probably not many but why not), here is my system:
    Antec Mini p180
    Corsair TX750 PSU (wish I had the $$ for the 1000 watt model used here)
    LG GGC-H20L Combo Blu Ray Drive (same used)
    WD 640GB Caviar Blue - placed in top optical drive slot - working on VR 300GB
    6GB Corsair Dominator DDR3-1600 (saving for the Dominator GT DDR3-2000)
    Dominator AirFlow Fan (triple channel model)
    Intel Core i7 920
    Lapped TRUE
    5x Scythe S-Flex G fans (2 on TRUE, 1 exhaust, 2 intake in place of hard drive cages)
    Thermaltake Extreme Spirit II Northbridge Cooler
    2x EVGA GTX275 SLI (the SC models, even though I purchased stock clocks :))

    This system hauls some serious ass, well staying reasonably cooled - although I will say that the S-Flex G fans have a noticeable hum to them. This system has run for days at 4GHz (50% overclock) with no issues.I "only" game on a 24" screen so the 2x GTX275 suffice for me. Thought about 295's in SLI but did not want to worry about the heat those can make (and the much higher cost).

    of course, I will still try my luck at winning theirs too......

    Lol, I love the firewire solution. :P I do that kind of thing all the time.

    I'm actually really impressed with this machine for it's size. I've used that silverstone exaust fan in quite a few machines, and despite it's totally uninspiring performance, it can really be a life-saver.

    Though if I won this machine, I'd totally throw it in a HAF, and ebay that case away. :P:D

    I really appreciate the unusual board choice and would really like to hear some further impressions, as in an actual review ;)
    The case looks very nice, but then Silverstone always does.
    A bit surprised at the PSU selection given the cards, but impressed that it survived so well.
    Couldn't a higher RPM low profile heatsink have been found? Scythe Shuriken for instance?

    While I'm not loving the case design, I am loving it's layout. Too bad you had to use the box cooler... Perhaps a Lian Li PC-A05B would have been a better choice? It needs the optional PCI cooler assembly to keep the slots area cool, but it will do the job, while not limiting you to a mini-ATX board. It will also allow almost any aftermarket CPU Cooler (including some WC setups).

    Another small gripe... wouldn't the 640GB Blacks be just a little faster then the 500GB RE3's? They might not get the full 5 yrs warranty, and the 24/7 validation seems more like a marketing term.

    Don't get me wrong, I do get the vibe... don't use big-ass cases for gaming rigs anymore. It is true that bigger isn't always what you need, and it shouldn't be what you'd want.

    Overall nice setup.
