CPU and Motherboard Recommendations

CPU: AMD Athlon 64 FX53 1MB L2 cache (2.4GHz) - SOCKET 939
Motherboard: MSI K8N Neo2 Platinum - SOCKET 939
Price: CPU - $829 shipped (retail heatsink and fan). Motherboard - $145 shipped

For those looking for the best performance possible, it would be tough to recommend anything other than the Athlon 64 FX53. The Athlon 64 is currently the fastest processor that you can buy, the Dual-Channel Socket 939 is the top-performing A64 Socket, and the FX is the fastest 939 processor. The FX also has the distinction of being the only processor that is completely unlocked. That means that you can adjust multipliers both up and down, to obtain the highest possible speed at the fastest DDR400 memory timings, or to obtain the highest FSB that your high speed memory can run or your CPU can reach



With Intel's recent introduction of Socket 775 came a new 560 Pentium 4, which runs at 3.6GHz. While the 560 is closer in performance than the previous 3.4GHz P4 or the 3.4EE, the FX53 is still the top-performing CPU. In addition, all current Pentium 4 processors can only run 32-bit code, so AMD's Athlon 64 is unique because it can run 32-bit code as well or better than the top competition in addition to 64-bit code for the future. All-in-all, the FX53 represents a good choice if you are building a high-end system, whether in the newest Socket 939 or the older Socket 940.

We chose Socket 939 for the future, since this appears to be AMD's primary socket moving forward. Socket 939 also has the added feature of being able to use any of a very wide selection of commonly available unbuffered DDR memory instead of the harder to find and more expensive registered DDR required by Socket 940 motherboards. You will get almost identical performance at almost the same cost with the Asus SK8V motherboard, the socket 940 FX53, and OCZ DDR433 Registered DDR memory. These selections are proven performers and are only very slightly slower than the Socket 939 in any benchmark.



While they are just beginning to appear in the retail channel (finally!), the MSI K8N Neo2 Platinum stood out in our recent Socket 939 roundup as a top performer and earned the AnandTech Gold Editor's Choice. Perhaps even more important for performance, the K8N Neo2 was the only board in the 939 roundup to match and actually edge ahead of the standout memory performance of the legendary Asus P4C800-E in our overclock tests. The K8N Neo2 actually reached a Clock Frequency of 290 (DDR580) with fast DDR550 memory that we used in our overclock tests. Wherever you can take the FX53, the K8N Neo2 will go - to the limits of your CPU or memory.

When the day is done, the K8N Neo2 will continue to impress with a full implementation of the features of the nForce3-250Gb/Ultra including fast on-chip LAN, any-drive RAID that allows IDE and SATA hard drives to be combined in RAID arrays, and an on-chip Firewall. The feature set compares well to any premium Socket 939 on the market and will not disappoint. You can count on a working AGP/PCI lock with adjustments from 66 to 100, CPU multipliers from 4X to 20X, HyperTransport adjustments from 1GHz to 200MHz (5x-1x), and CPU frequencies from 200 - 300. You also get a full range of voltage adjustments - vCore to 1.85V, memory voltage to 2.85V, and vAGP to 1.85V. This is even a board for the beginning overclocker, since there are automatic overclocking selections in Core Cell that set everything for you. You just choose the % overclock from 1% to 11% and the board does the rest.

The MSI provides everything that you would expect in a high-end motherboard for the Athlon 64. Memory up to 4GB is supported in Dual-Channel mode. Support is also included for up to 8 USB devices and 3 Firewire devices. There is also a second Gigabit LAN port for added flexibility. On-Board audio is provided by the latest Realtek 7.1 ALC850 with SPDIF I/O.

We have never tested a perfect board, and as much as we like the K8N Neo2, there are still areas for improvement. MSI has answered one suggestion by providing an improved CPU frequency range to 350 in the latest 1.1 BIOS. Another improvement MSI could make is to provide finer adjustments for CPU ratios, providing 0.5X ratios like some of the competing boards. Last, there is no real voltage adjustment for HT or chipset voltage, and that would add to the flexibility. However, in the end, it's hard to complain about a board that does so much so well. The MSI is a great board to house the FX53 for the High-End system.

    Uff -
    The two FX53 I've tested both run fine at 2.6GHz (future FX55 spec) with stock cooling. While you will get more potential with better cooling, you are not locked out of using a higher multiplier just because you use stock cooling. The AMD Retail HSF does a decent job of cooling, though there are certainly better solutions available.
  • Uff - Wednesday, September 1, 2004 - link

    My point with FX-53 and stock cooling was exactly that: the main bonus you get with FX-53 is that it's multiplier unlocked but to make any use of that you need proper cooling.

    #40 - The DVD prices were pulled at slightly different times for the Recommended and Alternate systems. For consistency, both charts now show a $97 price for the Pioneer 108. Prices constantly change, so any published price will generally be off in a few days or weeks.

    Why is it that the DVD burner in the recommended high-end system costs $97 yet the exact same one in the alternate high-end system costs $96?

    every single time, these guides ignore 2 of the best PSUs on the market: the PC Power and Cooling 510Deluxe which is miles ahead of the antec. Also ignored is the Fortron 530s. In my experience, the Fortrons are at least on par with the Antecs of not equal.
    P.S. If you spend the money on an FX-53 you might as well get a server board and go with the 940pin version so you can plug in a SCSI RAID card and have an array of 73GB 15k drives....just my $0.02

    There is no "be all, end all" guide to anything, particularly in a rapidly changing technology environment. This guide is merely a guide. A place to start from, and go from there. They recommend getting the keyboard and mouse that is right for you, whether it be $70 or $10. However, I think there may be some logic in requesting that there's more of a reasonable scale from budget, mainstream, and high-end. This high-end guide tries to balance having enough money to buy the fastest computer with trying to make it affordable to a relatively wide audience, but really, I think there may be a different way to go about it. I think you could save a lot of money for a minimally slower computer, and by doing that, saving money for your next high-end machine. If you get the absolutely fastest machine, then there really should be no limits on money, and it should really be a no budget dream machine. If you're on a budget, even if it's $5000, you might want to be a little tiny bit stingier, and make sure that six months or a year from now, you still have a good budget for getting a high end rig.

    The only typo I saw was "could care less" in the audio section. Should be "couldn't care less".

    The guides are a lot of work, and I think they are somewhat reasonable starting points. I appreciate them, even though I don't really use them for my own purchasing decisions. They are interesting, and hopefully helpful to some people.

    How can you build a $3500 PC and then suggest a $10 mouse??? That's crazy! Lost a little respect for ya there.

    Uff - The improvements from Dual-Channel and 1024k cache vs. 512k cache are cumulative. So while either improvement alone is only 2 to 4% improvement, together the added cache and dual channel make the FX53 5% to 8% faster than the SC 512k 3700+ you suggest. If you want the top performance then the FX53 is the fastest.

    The FX53 is also completely unlocked, up and down, unlike the 3700+, 3800+, 3500+, or 3400+, which makes it possible to run at 2.6GHz for example at DDR400. All Athlon 64 are unlocked down, but only the FX is completely unlocked.
  • Uff - Tuesday, August 31, 2004 - link

    I'm just wondering why anyone in their right mind would buy an FX-53 and run it on stock cooling? Other than making more space in your room by taking out some of the spare piles of money, there is no real gain in it compared to say 3700+ (or even a 2.4GHz 3400+, since tests have shown little gain from the extra 512kb cache).

    I am surprised that you reccomend mere computer speakers for a high end system. A receiver/speaker system (albeit more expensive) would be more appropriate for a high end system. I realize that this is outside the scope of a computer buyer's guide, but I think anyone who truly appreciates music/sound/noise would be willing to spend the $500 for a set of speakers that will last a lifetime (speakers dont go obselete or break). Combined with a good receiver (additional $100) you can output amazing sound from the radio, tv, computer, dvd. For $500 you can get the amazing NHT SB3 speaker system or the Klipsch RB25's.
