AGP Overclocking Recommendation: eVGA 256MB GeForce 6800 GTPrice: $383 shipped
While the dust is still settling in this round of the video wars, we do know that the new generation of video cards from nVidia and ATI are twice as fast as the previous generation in many benchmarks. We also found in our testing of the new nVidia nForce3-250 chipset that it performs a bit better with an nVidia graphics card. With that in mind, we included a GeForce 6800 GT in our Overclocking system to match the nForce3-250 Ultra-based MSI K8N Neo2.
Why a GT instead of a 6800 Ultra? The 6800 GT is unique in also sporting 16 pipelines just like the 6800 Ultra. In fact, the only real difference that we can find between the 6800 GT and the more expensive 6800 Ultra is the clock speed. The two 6800 GT that we tested both reached 6800 Ultra clock speeds pretty handily, so if you want 6800 Ultra performance, you may well get it with a 6800 GT overclocked to 6800 ultra speeds. You can also buy 6800 GT cards, which is more than we can say for 6800 Ultras, which are very difficult to find.
The 6800 GT is clocked at 350MHz with memory at 1.0Ghz; the 6800 Ultra clocks the GPU at 400MHz, and the memory at 1.1GHz. Both have 256MB of DDR3 memory and 16 pipelines. The easiest way to try your hand at overclocking a 6800 GT to Ultra levels is with a widely available utility called Coolbits, which adds Clock Frequencies to the advanced tab of the nVidia properties. Coolbits even offers a Test and Optimal Settings button so you can check to see if your 6800 GT can support 400HMHz and 1.1GHz speeds.
If budget is a concern for your overclocking system, there is also a 12-pipe 6800 available for about $300. The 6800 is sill a decent performer and even easier to find, but it is not likely that you will push a 6800 to 6800 Ultra performance levels, and you will be still stuck with 12 pipelines instead of the 16 available with the 6800 GT and 6800 Ultra. There is also an even faster version of the 6800 family, called the 6800 Ultra Extreme, but as rare as 6800 Ultra cards are right now, we would hesitate to recommend an even rarer card, which is just a higher-clocked 6800 Ultra. Perhaps a 6800 Ultra, when you can find one, will overclock to Extreme levels.
The best way to see what the 6800 Ultra can do is to read the latest AnandTech Video Card review, which compares ATI X800 and nVidia 6800 in both AGP and PCI Express flavors.
The AGP Overclocking Recommendations will work very well on the MSI K8N Neo2, DFI LANParty UT nF3 250Gb, or Chaintech VNF3-250. However, a PCI Express Video Card is required for the Socket 775 Asus P5AD2 Premium.
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.

For ram, look into PQI's 2-2-2-5 (2x512mb) solution. It overclocks really well with relatively tight timings and has samsung's tccd chips. It's also cheaper than other solutions ($250)axel - Friday, September 17, 2004 - link
Hi, very interesting article indeed.The only thing I do not really understand, and rather see as an error is the following:
You say that almost every top overclockers i.e. in the futuremark 3dmarks ORB database are on AMD platforms. Though, except if I'm not looking at the right place, if I'm taking into account the 5 best scores, I see that 4 of them are running Pentium4 platforms, and only one is an AMD (which is actually on the 4th position of the top-5).

Id like to see how the XP stacks up against the 64 when overclocked.. I have a XP mobile 2600 and am running it at 2.46Ghz and everything I throw at it runs as smooth as silk.. I dont see a need to upgrade unless there was something I couldnt run, or run smooth.eetnoyer - Friday, September 17, 2004 - link
Any chance you've tested the limits of the ballistix RAM on the DFI. If so, how high did it reach?Nickel020 - Friday, September 17, 2004 - link
Nice article, but there is a mistake on page 5 (CPU and Motherboard: VALUE OC Recommendations):The heatsinks listed (XP-90 & 120) are made by Thermalright, not Thermaltake.

Nice article, though I'm curious to see how the 3200-M64 performs compared to the Clawhammer and Newcastle desktop cores. I know the Newcastle revisions have an upgraded memory controller, or something like that; does the 3200-M64 have the same upgrades, or is it based on the older Clawhammer revision?And why the choice of OCZ's PowerStream? Antec puts out a 550w that's just as reliable as the 480w you suggested as an alternative... Unless I missed a review that pointed out the OCZ to be more robust than the Antec supply.

This is my type of review. I can't have too many of them. I do agree with slashbinslashbash about some guidance on value oriented RAM. The price differences between 2-2-2-5 memory and say 2.5-x-x-x value memory is rather drastic. But if none of it will o/c then so be it.slashbinslashbash - Friday, September 17, 2004 - link
#2: Under the Value OC Alternative system Wesley writes "Buy an ATI 9800 PRO for $200 less and overclock the heck out of it." So it looks like you were right on the money ;) Personally I'm looking at a 9600XT All-In-Wonder as it's about the same price at Newegg; less performance in games (still reasonable framerates in Doom3) but with the ever-so-cool All-In-Wonder functionality added.slashbinslashbash - Friday, September 17, 2004 - link
Great guide. The only thing that I'd ask you to do differently (or rather, to add next time) is to make a "value" recommendation for the RAM. Nowadays I won't use any less than a gig of RAM, but I think it's silly to pay substantially more for RAM than for the CPU. Even just one stick of 512MB in the Value Alternative system costs more than the CPU.I'd like to know some "value" RAM alternatives that might not have such aggressive latency timings but will still keep up with the mobo and CPU, if it's possible. I know you guys can't test every cheapo stick of RAM out there, but... any sort of guidance would be appreciated. All the big brands offer "Value" RAM. Will none of it overclock? Is the performance from the recommended $280 (for 1GB) RAM actually worth the $120 premium it commands over, say, two $80 sticks of Corsair Value Select (on front page of ZipZoomFly)? Would that $120 be better spent on the CPU? It's more than the difference between the Sempron 3100+ and the "Value Recommended" system's A64 3200+.. and it nearly covers the upgrade to both the CPU and motherboard.
Also, two errors: 1) the eVGA 6800GT is listed as $389 under the Value Alternative system but at $383 under the Value Recommended system; 2) the Value Recommended system sums to $1440, not $1460.
Again, great guide, it's probably what I'll be looking at when I decide on my next system.

For AGP VGA, do you have a value altervative for limited budget not playing doom3?For me, 6800 is too powerful to run multimedia and encoding DivX.
Do you think 9800Pro can be runner up?
Anyone knows about when ATI X series for AGP (X300, X600) will be coming? or ONLY PCI Express :'(
