CPU and Motherboard Alternatives

CPU: AMD Athlon XP 2500+ (retail)
Motherboard: ABIT NF7-S Rev.2 (nForce2 Ultra 400)
Price: CPU - $80 shipped (retail). Motherboard - $98 shipped



Prices on Athlon XP 2500+ desktop processors have stayed exactly the same since the last time we checked them 4 weeks ago. So, like before, an additional $26 (compared to a 2000+) will net you an Athlon XP 2500+ that runs at 1.83GHz on a 333MHz DDR FSB and comes with a 512K L2 cache. In contrast to the Athlon XP 2000+, the 2500+ runs roughly 167MHz faster, comes with double the L2 cache, and has a FSB that is 67MHz faster. All this adds up to noticeably better performance, though depending on what applications you run, you may not notice it. Still, there's no denying that if you're willing to spend a little more, you will definitely be getting a better performing processor.

Other differences between the Athlon XP 2000+ and the 2500+ is the 2500+'s higher Vcore (1.65V instead of 1.60V) and larger die size. Another nice thing about this processor is that it's quite an excellent overclocking CPU, and has been for months now, even if they are shipping multiplier locked these days. On a side note, this is the retail version of the 2500+, so your HSF (heatsink and fan) cooling is included for $80 shipped.



Like the 2500+ desktop version of AMD's Athlon XP processor, the ABIT NF7-S Rev.2's price hasn't changed at all in the last 4 weeks. The NF7-S Rev.2 is a better budget board than the A7N8X-X due to its better feature set (SPDIF, MCP-T South Bridge for superior sound), but it lacks a price as competitive, at $98 instead of $69, like with the A7N8X-X. $29 is quite a large difference, but if you don't need better sound and/or SPDIF, then you have absolutely no reason to pick this motherboard. Though, if you're an overclocker, you have every reason to look at this motherboard, but that's probably not the case if you're reading an entry level guide like this one.

    Here's something that was missed, I think. When talking about the RAM, they mention the CAS 3.0 vs. CAS 2.5 or whatever. However, they're using a 133 MHz bus (PC2100 RAM).

    Now, correct me if I'm wrong, but if you have PC3200 RAM with 3-3-3-8 timings, it should run perfectly well at PC2100 speed with 2-2-2-6 or possibly even 2-2-2-5 timings. Why? Well, 3200 is 52.4% more than 2100, and 3 is only 50% more than 2. Right?

    Anyway, back in the good old SDRAM days, I remember picking up some CAS3 "PC150" RAM and running it at CAS2 since I had a 100 MHz bus speed at the time. Funny thing was that PC150 was cheaper than PC100 with CAS2. Seems like that's happening in the DDR market now.

    seems like the 512 mg of ram is a pretty universal idea....

    And I agree with whoever is saying that celerons suck ass. "value" and "celeron"? LOL!
  • Etacovda - Sunday, April 18, 2004 - link

    Not a bad choice - ive made similar systems in the past. For a value system, why not get a 40gig WD SE drive... without filling the system up with wares, im sure that would be enough for most uses ;) i doubt they will be buying 10 new games to put on it as that comes to about the same price as the system.

    Great choice on the mobo, there is only 2 gripes i have with that board - the caps are very close to the socket for aftermarket cooler installs, and for some reason the one i had hated mbm5.

    512 of ram is a good idea - theres a 'value' system, then there is just building the cheapest system you can build... there is a difference :p

    While I have admired the styling and pricing of the manufacturers of the cases you are recommending for some time, I would never purchase one. The reason being because of the severe air flow restrictions imposed on the rear case fans.

    I can't imagine how any air could even begin to go through those little tiny holes.

    With quiet systems becoming very much desirable these days, I would like to see some cases that could meet those expectations in your guides.

    The quietest fan becomes noisy when the air has no place to go.

    If you are building a value-level rig and a customer "has to have Intel" then you have one seriously dumb customer. I mean, fanboys and the perennial fight aside, the value market has always belonged to AMD and a Celeron is a horrible processor to sell anyone when a comparable speed Athlon XP is actually cheaper. And don't say the PR ratings are off when the XP's have more L1 cache than all of the Celeron's L1 and L2 combined...read any review on any decent tech website and you will never see a Celeron in any section but the "stay away from these processors" part. Point is I could never sell a Celeron-based system to a customer I would feel like I was cheating him.

    #10 - Celerons are awful CPUs. I wouldn't put one in a system if *Intel* payed *me*... well, maybe then, but anyway... ;)

    512 MB ram should be the minimum put into ANY system these days, period. I don't agree about using a mATX nForce board, just because they haven't seemed very stable to me - maybe I just haven't found the right memory to use with one, but it's not like I used cheap memory. I think in most cases that onboard video causes more problems than it's worth - if they had dedicated video memory built onto the mobo, that'd be one thing, but I'd rather not have it using up system memory.

    I'd also agree that going with one of the Antec cases (SLK1600 or 3700) or something similar would definately be worth it. You're better spending a little more and having a system that's stable and problem-free than going too cheap and running into problems. But hey, the "techs" out there building these cheap systems are keeping me in business, since I'm always having to replace cheap parts with quality ones when they die a year later.

    Are SFF designs getting close enough in price for consideration in your monthly budget/mid-range system reviews?
  • thebluesgnr - Saturday, April 17, 2004 - link

    I would replace the motherboard with the MSI K7N2 Delta-L or ABIT NF7 2.0. They cost the same as the ASUS and have better quality (nForce2 Ultra 400 and better power solutions). Specially the ABIT has better quality.

    Dual channel doesn't make much difference but it's likely this system will be upgraded in the future with another stick of RAM so getting the nForce2 Ultra 400 for no extra money at all is a no-brainer imho.

    You may also consider a SiS 748 based board. You can get the ASRock K7S8XE for only $51 shipped (newegg.com) or the Gigabyte for only $54. But the ASRock is on-pair with the "-X" series boards from ASUS as far as components quality goes.

    BTW, most mini-ATX NForce2 400 IGP board do come with a AGP port. So, the user always have the option to a better graphic card.
  • yanon - Saturday, April 17, 2004 - link

    To be a true entry-level machine, it should have an integrated motherboard. Any one of those mini-ATX NForce2 400 IGP board with GF4MX video and Cmedia 6 channel sound should be fine. Granted that this type of motherboard will only have a 3 pci slots, but an entry level does not need all those expension slots because people who will buy this type of machine just want to surf the web, listen to mp3, some word processing, basic digital photo editing, and occassional gaming (mostly online java-based games). My cousin can play MOHAA on such a machine. 512 Mbytes of ram is a must and NEC 2500A 8X DVD+/-RW drive should also be part of this system since DVD burning is rising in popularity as the cost for a 50-pack Ritek 4.7G DVD-R is only $40 on Newegg now. Entry-level computer builder should consider using the $50 silver Enermax (including a 350watt powersupply) since it has that expensive aluminum look and 2 frontal USB jacks plus audio/mic jacks. Another advantage of using this case is that it has lots holes in the lower portion of the front panel. Moving the back fan to the front will provide ample cooling to all the components inside. All buyer should consider spend extra $20 to buy a retail cpu instead of an OEM cpu since retail comes with a heatsink-and-fan and 1 year warranty. Buying a cheap heatsink and fan unit for the oem CPU will cost you at least $10 more and without an 1 year warranty for the CPU.
