CPU and Motherboard Recommendations

CPU: AMD Athlon 64 FX53 1MB L2 cache (2.4GHz)
Motherboard: Asus SK8V (VIA K8T800)
Price: CPU - $731 shipped (retail heatsink and fan). Motherboard - $171 shipped



This was a difficult choice when the high-end selections were Athlon 64 3400+ (2.2Ghz), Athlon 64 FX51 (2.2GHz), Pentium 4 3.4C, and Pentium 4 3.4EE. However, the introduction of the FX53 brings us the only current Athlon 64 at 2.4GHz, which makes the FX53 the fastest CPU you can buy. Selecting the FX53 was only a concern because the introduction of Socket 939 is just around the corner. Yes, Socket 939 will be here next month, but the FX53 will still be the fastest Athlon 64 that you can buy; there will just be an additional FX53 for Socket 939. As you had read in our AMD roadmaps, there will also be a 3800+ for Socket 939 with 512KB cache instead of the 1MB available on the FX53 chips, so you know that the FX53 is blazing fast and faster than a 3800+ will be. In addition to the fast 32-bit performance that we found in our review of the FX53, the FX53 also supports 64-bit computing for the future. Prices have also dropped a bit so that the FX53 is about $300 more than a slower 2.2GHz 3400+. While that's a big price difference for a CPU, it is really fairly small in building a high-end system. The FX53 is also now 30% cheaper than Intel's top 3.4EE, which costs over $1000. Furthermore, 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 today. If not, wait a few weeks and consider this same FX53 in Socket 939 clothes.

For the Socket 940 FX53, there is no better choice than the Asus SK8V. In our roundup of Socket 940 motherboards, the SK8V out-paced the competition in almost every benchmark and earned our Gold Editor's Choice as the best Socket 940 motherboard.



The Asus SK8V earned Editor's Choice because it is simply the fastest AMD motherboard that we have ever tested. Wherever the SK8V is benchmarked, it has earned an Editor's Choice for the kind of legendary performance that makes it the ideal heart for a High End system. Don't confuse the Asus SK8V with the SK8N, which is built on the nVidia nForce3-150 chipset. The VIA K8T800 performs much better than the nF3-150 on the more demanding Socket 940 Dual-Channel platform.

The Asus SK8V is fully decked-out as you would expect from the Asus flagship board for Athlon 64. Features include dual RAID capabilities with both VIA SATA RAID supported by the VIA 8237 and Promise 20378 IDE/SATA RAID. You will also find on-board 6-channel SoundMax audio from ADI AD1985 that includes SPDIF connections, 8 USB 2.0 ports, 2 Firewire 1394a ports, and an Asus WiFi slot for wireless capabilities. An added bonus is that the Athlon 64 FX processors are completely unlocked and the SK8V supports this well with CPU ratios from 800 to 4000 in 100MHz increments. Whatever your FX-53 can do on overclocking is supported on the SK8V. Asus has lavished every top-end feature in their huge arsenal on the SK8V and it definitely wears the features very well. As a personal testimony, the SK8V is a favorite motherboard with Anand and Derek in our Raleigh, NC labs and with me in our New York labs. The best recommendation we could possibly make is that the Asus SK8V is the heart of two of these personal systems.

For those not comfortable with the ECC Registered memory requirements of the Socket 940 for Athlon 64 FX and Opteron, the recommendation is the MSI K8N Neo Platinum or one of several other excellent boards based on the new nVidia nForce3-250 chipset. While VIA may own the performance crown for Socket 940, nF3-250 owns the crown for enthusiast features on the Single-Channel Socket 754. All of the nF3-250 boards that we have tested have working PCI/AGP locks to get the most from any CPU and memory that you choose to use. More information on the MSI can be found in the K8N Neo review. For the Socket 754 Alternate, the Athlon 64 3400+ gets our nod.

    Other than encoding, which is the only area the Intel camp has a lead on the AMD64 chips, a Pentium 4 3.4GHz Extreme Edition is outpaced by the FX-53. How then can you make claims the Xeons would be better? For dual systems, no matter which camp you get your processors from, a single processor-based system of the same type is faster in most of today's games because they don't support dual-processing. Now, the latest and new generations of games are, so purchasing a dual-board with only a single CPU may be an option. However, the Xeons still only have a 533MHz FSB, so memory bandwidth is severely limited with the Xeons in comparison with an AMD FX or Opteron system.

    Good riddance, Xeon.

    #37, I think you're completely wrong on a few points. First of all, the *only* area where Athlon 64/FX don't easily compete (and often beat) Intel is in the encoding benchmarks. News flash: games DO NOT do any video or audio encoding. Secondary news flash: encoding/decoding is one area that benefits tremendously from native 64-bit integers. Hyper Threading? It's okay, but 64-bit is more important in encoding. (Look up some 64-bit benchmarks if you don't believe me.)

    SSE support? Well, Intel is probably better, but SSE support is still not the be-all, end-all of technologies. (And the 64/FX is a lot better than the old Athlon XP at SSE, partly because it supports SSE2.) Hand-coded SSE is fast, but a lot of people don't bother with hand coding anything. All 64-bit compilers give you 64-bit integer support, but not all 32-bit compilers can generate decent SSE/SSE2 code (if they generate any SSE at all).

    R420 vs. 6800 is an interesting debate, but the X800 Pro is available NOW while the 6800 - ANY 6800! - is still unavailable. As the article pointed out, this battle is not yet decided, but for now the only available cards are the X800 Pros. SM3 may or may not be important - especially considering that some of the games coming out with SM3 patches (Far Cry) are currently running 95% of their effects in SM1. SM2 can do 95% of the stuff that SM3 can do, so SM2 patches might be a better plan.

    Finally, two 3 GHz Xeons might indeed be cheaper than an Athlon FX-53 or a P4EE, but they are only good for SMP capable programs. Encoding would be faster, 3D rendering in programs like Lightwave and 3D Studio would be faster, but gaming would be markedly slower. Either the FX is a great choice for gaming, or a dual-Xeon (or dual-Opteron) would be a great choice for professional work. But you can't criticize the choice of the FX for "future gaming performance" and then whine about the lack of SMP two paragraphs later.

    With this system, you build something for a future that may never come, because the Athlon FX is build to make todays games run faster, but for tomorrows games it may well be a lame duck, because of its lack of raw encoding power, that could be very important to make games look better, while todays games do not gain much on a fast CPU yet.

    Furthermore, the R420 graphics adaptor may have to run in compatibility mode as soon as next month, when the first patches for PS 3.0 become available.

    Also, fast harddisks are hardly used in real world situations, except for heavy duty encoding, where the chosen CPU lags behind because of its lack of HT and its meager SSE support.

    So I would suggest to wait for the Geforce 6800, because of its (usable) better feature set and I think that dual Xeons will make for a much faster real world experience in about any task, while two 3 Ghz units are less expensive than a single 2,4 Ghz Athlon FX and mainboards are available in the same price range as well.

    SUPERB! High End should be High End and you finally got there. But I still believe that High End should also include 15K RPM SCSI 320 on a fast buss MOBO and that mid-range should include 10K SATA? Drive performance dramatically effects the noticable quickness of a PC and is much over looked by most folks!

    That is why we also have Buying Guides for Entry Level and Mid-Range systems. Yes, at 2.4GHz the FX 53 is faster than a 3400+ at 2.2GHz. It is both a higher clock speed and a Dual-Channel memory processor.

    For every complaint that our High End is too expensive, I have 10 complaining that we haven't spent enough for a high-end system. Value is ALWAYS a real concern at AnandTech, both in reviews and in all our guides. As I stated in the review, performance is my first concern here - within reason.

    You should look at Evan's Entry and Mid-Range Guides for your $500-$1000 budget suggestion.

    It seems that we are having issues with the definition of a "High End" system. Of course, everyone is entitled to their own opinions. Wesley, you have made an overall excellent technical article but what I think people have been getting at is: "How can we use this?"

    When you define High-End as "the best performance that you can buy for a given need," it fails to take into account some issues.

    As you briefly touched upon in your article, for every increase in performance, you spend significantly more... eventually you have diminishing returns, as putting in $100's yields a tiny percentage of performance gain.

    (But when you allow for $5000 in spending you will confirm again and again to our great surprise that the most expensive parts will indeed yield the best performance).

    When I come to AnandTech.com, I come for two things: technical information, and judgment calls from very experienced and knowledgeable people.

    What I want is YOUR judgment call. Should I pay hundreds more for an A64FX when there are A64s (or P4's, or AthlonXPs, etc etc) that are so close in performance? Would you be able to easily justify such a cost? Where on the price/performance curve should we target?

    There are no easy answers to these questions. These questions are tough to answer. I definitely appreciate that you are trying to give solid, fact-based advice that is hard to dispute. But that is not why people read guides.

    The thing is: if you can't/won't answer these questions, how can people who have a fraction of your experience be able to? So what I want is for you to go out on a branch and say "I think this is the best point on the price to performance graph, therefore this product is best."

    What I think would help you focus is to tackle the problem they way a buyer does: Allot a budget. What I mean by this is: "I want the best [gaming, workstation, etc] system I can get for [$500, $650, $800, $950, $1100, and so on]."

    Why make increments so small? Well, I think the toughest buying decisions are in range of 500-1000. To get the most out of their systems, people need to know where to spend the money.

    I know that working under the constrained budgets will make these guides HUGELY helpful. When people set out to buy computer parts (or most things for that matter), they typically work out what they can spend first, and THEN go to buy the best they can get.

    #30 - I have not ignored the Stacker at all, and I'm also impressed with the Stacker design. I did consider it, but it is pretty industrial-looking and better suited for the Overclocking System in my estimation than for the High End System. Overclockers tend to hang on to cases and move a lot of hardware through a case so the ATX/BTX makes a lot of sense in that situation.

    What I'm saying is I would buy a stacker for myself, but I would more likely recommend the elegant Praetorian or maybe even the slick blue-lighted Wave for a High End system.

    To be frank, I am reworking the audio and speaker sections for the next Guide, it is just the Guide is huge and I decided to delay a rework of those sections until the next installment. There will also be further updates to the Monitor section.

    I have to say I enjoy reading the System Guides as a way to stay on top of the top performaing hardware, but I find that some of the really new stuff is overlooked and future technologies are sometimes ignored, which could result in buying a $3000 system that will be outdated in months.

    I also cannot see how you can leave out the Klipsch Promedia Ultra 5.1's in your audio systems. At a price less than half of the GigaWorks, they offer top end performance greater than any existing logitech system and have available SWS sub daisy-chaining.

    On a similar note, you have ignored the availability of the first BTX compatible case, the CoolerMaster Stacker, which is not only a fantastic and well built ATX case, but can be reconfigured into the BTX format for later use.

    Also Dell's 19" lcd has a lower 16ms response time and has IQ much higher than most others, while not breaking the bank at about $800.
