PCIe Overclocking Recommendation: ATI X800 XT Platinum 256MB PCIePrice: $531
After several months of very limited supplies, the ATI X800 XT with PCI Express bus is finally becoming a bit easier to find. If you are an overclocker looking for top performance on a new Intel 925X board, the X800 XT is the best option at the present. Unfortunately, the ATI X800 PRO is 12 pipelines instead of 16, so more than just overclocking the video card is required to reach X800 XT performance levels. If you're set on a new Intel 775 system for overclocking, then you need to get in line to buy this card.
There are X600 XT PCIe cards available from several vendors and they would be a good alternative if your overclocking goal is to reach the highest speed possible with a 775 platform. We are finding the ATI PCIe cards to be more tolerant of out-of-spec PCIe settings on the 775, so the X600 XT should allow you to reach the highest overclocks possible in the new PCIe systems. However, you will need the X800 XT if your goal is to achieve the highest overclocks combined with top video performance at those rarified overclocks above 250 to 260 clock frequency.
As we have pointed out in the past, you can choose either the X800 XT or the 6800 Ultra and be perfectly happy and perfectly competitive in the performance area, but for overclocking PCI Express, we have found that the ATI cards simply survive to higher PCIe overclock levels.
Listed below is part of our RealTime pricing engine, which lists the lowest prices available on ATI video cards from many different reputable vendors:
If you cannot find the lowest prices on the products that we've recommended on this page, it's because we don't list some of them in our RealTime pricing engine. Until we do, we suggest that you do an independent search online at the various vendors' web sites. Just pick and choose where you want to buy your products by looking for a vendor located under the "Vendor" heading.

Perfect timing and very infomative article. I'm looking to buy a MSI K8N Neo2 Platinum w/ an AMD 64 FX-55 cpu.How would Crucial Ballistix PC4000 2.5-4-4-8 compare to PC3200 2-2-2-5 on the MSI mb? Faster bandwidth ver tighter timings?

Thank you, Fink.I ran Athlon64 Mobile 3200 2.0@2.55 Vcore 1.8
I will drop to 10x250 vcore1.7 for safer :>
Ballistix run@ 1:1 2.5-4-4-8 (I don't want to set 2.5-3-3-5 like the review for make sure that it works fine)
I'll tell the testing result again.
P.S. I had reached to 10x260 V1.8, windows works but Prime95 doens't work stable.

Wesley,If Raid 1 is used (mirrowing), is the slow down negligble for a simulations gamer - or would it be noticable? Would the same be the case with 7,200 rpm SATA's?
I also notice that you listed the eVGA 6800, but the July High-End Guide listed the Gigabyte 6800 (Ultra). Have you noticed performance or manufacturing differences between the 6800 vendors?
The photo of the Crucial Ballistik PC3200 512 memory has a CL113V.X1 part number on it. I can't find that part number listed on the Crucial web site. ? Bill Mackay

This is one interesting article, but I wish it had the same idea of a "Value" system as other AT articles. The Value system of this guide is too much for me, here's what I came up with:AMD Athlon XP Mobile 2400+ 45W $77
ASRock K7V88 Raid $44
512MB (1 X 512MB) Corsair Value Select DDR400 CAS2.5 $79
128MB GeCube Radeon 9550XT $99
Antec SLK3700-BQE Black ATX Midtower w/ 350W PSU $90
Seagate 80GB 7200RPM SATA (8Mb Cache) – ST380013AS $71
HSF not included, total of $460.
One could change that system to a Chaintech VNF3-250 + Sempron 3100+, but I would rather upgrade the video card first.

#25 Wesley Fink- its great to hear a Value RAM roundup is being planned, listening to and where necessary addressing your readers comments is one of the main reasons AT is such a valuable website.Gholam - Saturday, September 18, 2004 - link
You have a mistake on page 13 - you list CM Stacker as an all-aluminium case, while it definitely isn't. It has aluminium panels, but the chassis frame is made of steel. It also weighs 14.9kg... ouch. On the other hand, there is no other case where ducting the PSU is as easy...Wesley Fink - Saturday, September 18, 2004 - link
#24 - I mentioned in the Value conclusion that you can cut $300 by choosing a cheaper case and an ATI 9800 PRO instead. Perhaps I should make those recommendations part of the Value OC chart in the future.#22 - I recommended one 512MB stick of Crucial Ballistix to get the cost down on the lowest priced system and still have great overclocking. We do plan a Value RAM roundup in the future.

Wesley,Keep up the good work!
Only nit is that like last time, you "forgot" (maybe it was intentional) to present a value video card. The price of the video card stuck out like a sore thumb in the summary pricing table for the value system!
The power requirements are ugly, but consider putting the 9800pro in the summary table for the value system next time. Until the X700XT and 6600GT's come out (and in AGP), you can't do better for $190. [Or at least you could have downshifted from a 6800GT to a 6800 to save a hundred bucks on the value system.]

you know what would kick arse? doing comparison tests! Compare all the different rigs you guys reccomend and see who the winners are. i.e. Performance OC vs your high end setup etc.PrinceGaz - Friday, September 17, 2004 - link
I really don't know why anyone here is so keen on the Sempron 3100+. You'd be a fool to buy one when the A64 2800+ is available at only a slightly higher cost, has twice the L2 cache, and most importantly 64-bit support. Anyone who buys a Sempron 3100+ today will regret it in a year or two when x86-64 Windows is supported.If you only keep a CPU for a year or so though, it makes even less sense getting something like the Sempron 3100+ with hopes of high overclocks unless you like always having an overclocked substandard processor.
The non-high end memory issue is important and really needs to be covered, CAS 2.5 modules form the likes of Corsair are available at very competitive prices compared to CAS 2 modules. We need an article that looks at CAS 2.5 and also CAS 3 PC3200 modules from the major manufacturers so we can see how far they overclock, and at what voltages and timings. Most people don't buy CAS2 modules unless they're getting a top of the range CPU (2.4 GHz A64 or 3.2+ GHz Prescott), so if you look at an A64 3200+, you need to look at the memory most people will use with it.
