Tom's SBM: The $1,500 Mainstream PC

Meet Our CPU, For The Last Time

Yes, once again—though likely for the last time—we chose the long standing people’s champion of quad-core CPUs, the Q6600.

Read Customer Reviews of Intel’s Core 2 Quad Q6600

This decision might surprise the dual-core fans out there, who believe that the E8400 would be a better choice due to its overclocking capability. And we agree with you, but we wanted to give the Q6600 a final kick at the can to see what a newer G0 revision core could accomplish. The Q6600 we previously tested was an old sample, so we got our hands on a brand new CPU to play with to see if it would overclock better than our old workhorse.

While the Q6600 has gotten a little long in the tooth, its 2.4 GHz stock speed and four processing cores are still no slouch ; they are known to overclock at least 1 GHz over that frequency pretty reliably. With the new stepping, our hopes were to approach the 3.7 GHz range. Our previous sample seemed to become unreliable at anything past 3.4 GHz, so we’re going to see if we can squeeze some extra MHz out of this new toy with Swiftech’s excellent H20-220 water-cooling kit.

  • Hi,
    This is my first comment although I have reading this website for the past 8 years. Anyway to th point - Usuallt I agree 90% with you on components you choose, especially in the high-end and budget configuration. But this time a lot of tings strikes me: First it is the CPU - I am pleased You have addressed the issue to a great degree in the article later, but still I think it will be appropriate to try to further increase the voltage because this is a watercooled 65nm CPU; Second the chipset I think it`s ot the best choise, X38 is a former high-end chipset so when You`re overclocking you should get the faster binned X48, but because this is mid-range configuration I think it`s best to taka advantage of the super popular P45; Third the motherboard I am not sure if a motherboard with a not so stron PWM is the best tool for overclocking such a power-hungry chip, You should try to overclock on a different motherboard to see why are yuo`re not receiving a more descent overclock;Forth and last the price difference to a 1066MHz kit is pretty small so I think it`s preferable because tis will give You flexibility to try higher FSB with lower multiplier, wchich should give another notch of performance. I am saying all this because I want to help You make this website even better.
    Best Regards. Bobby

  • I think it would be interesting to see power consumption and noise benchmarks for the PCs you build in this article series.

    I can see why you wanted to use a water cooling kit so that you got the best possible overclock from the CPU but water cooling is hardly ‘mainstream’ which is what I thought this system builder marathon was all about. The same goes for the choice of motherboard, the X38 is an enthusiast’s motherboard, something like the Biostar T Power i45 would have been more appropriate and according to CustomPC UK is just as good at overclocking as any other motherboard.

    Good choice in video cards, I’m glad you didn’t choose 4850’s with the stock coolers because those bad boys run really hot.

    Well it was a good try. Would have preferred a more truly mainstream rig, but then the forums are full of those.

    And I thought a $400 Dell or E-Machine was mainstream..

    P45 wouldnt have workd cos it would bottleneck the crossfire as it only runs at 8x and 4850's need 16x

    I agree with this dude really. Anything watercooled is enthusiast, not mainstream. I don't know if americans just treat themselves to better hardware, but here in europe anyone with watercooling is considered an enthusiast. Nobody with a reasonable budget is going to 'waste' money on water cooling. Imo a tuniq, tr120 or a scythe something cooler would've been a more appropriate midrange guess. Also I'd expect anyone building a pc today to pick a p45 over an x38 (though I like the red slots on this one)

    A E8500, single socket P45, HD4870x2,Sunbeam core contact cooler and a Coolermaster 690 would have made their budget and blown the socks off that build.

    How about some info on this "mainstream" system sound wise. How Loud or quite is this system use this Swiftech H20-220 Kit with larger pumps etc. Also what's the temperatures like (heat dissipation) like in general with this combination please?

    I know most ppl are probably more interested with the benchmarks, but I'm sure this might interest some people on what's it like to live with, thanks!
