The Intel 815 boards are not necessarily supporting Tualatin cpu's. There are other chipsets that support Tualatin like the VIA Apollo Pro 133T and 166T. Check out this overview for starters - Tualatin support is listed in the [edit] 4th column.

This is amazing! Exactly the sort of thing I was looking for. Cheers Parke.

This bundle looks perfect. The mb is included on the Tualitin supported list, plus it comes with the CPU I want, and some RAM:

Tied and true, ASUS TUSL2-C motherboard..... if you can find one for a decent price.

The cpu on that board looks like a regular 1.4 Ghz version but it is difficult to see.
You would want the "S" (server) version with 512Kb cache. Look for one of these CPUID numbers:
SL5XL
SL657
SL6BY
SL6JP
Also, two of the VRM capacitors on that board look suspect: numbers 7 & 8 counting from the left.

How much of a difference does the extra cache make? Would it be very noticeable for gaming?

Thanks for pointing out the caps, I will take note.

The extra cache will make a minor difference. a couple of FPS in games. There is a few extra Instructions tacked on as well that may or not be noticed when running some windows apps.
It will however give you a Bosting point that you have the Fastest and Best P3 cpu!

Hahaha well when you say it like that, all of a sudden the boasting rights seem like reason enough 😎

If you want the best of the best, take the -S version. It usually also overclocks very good when paired with a good motherboard.

Also don't forget to use some better video card with it. It's better to have overpowered video card 😉

All though the i815 chipset doesn't handle more than 512 MiB of RAM, I would go for an i815 based Tualatin compatible board .. In that era, Intel chipsets were just so much easier to cope with drivers-wise than anything else, IMO ..

I agree on that one!

I'm currently running a Geforce 2 MX400, but would like to run games such as Morrowind and Deus Ex. I hear that my current card may struggle with these.

I would greatly appreciate any suggestions for video cards which would pair well with the Tualitin CPU for maximum performance.

Thanks, as always.

I'd use something in the line of Geforce Ti4x00. Ti4200 128MB will be more than enough. But some might want Ti4600 or ATi 9700 or 9800 Pro. Using newer video card gives you a choice to use AA and higher resolutions than period correct ones. It's just a better gaming experience 😀

If you search for TualAtin you will find more hits 😉

Just an impression of possible scaling - it can be done better. To measure the capability of this type of videocard you would want to use, for example, 3DMark 2001.

Most Intel 815 boards share major flaw - no ISA slots.

Like Vogons member VooDooMan concluded:
"There is no ideal Tualatin Motherboard"

Fastest Tualatin Chipset / Best Pentium III Motherboard

I have TUSL2-C with S model and voodoo5500 and vortex 2 and USB2 card.

It is really good combo for glide (98-ME) era. I used to run this with GF2 ultra which was also good option - I bought these when those were new.. If one cal live without 'real' dos in which 1400Mhz p3 is a bit too fast anyway, combo I have is good option.

Also TUSL2-C has universal AGP which can run V5 series if you have them.

Why are ISA slots so important? Is it just for having a DOS era sound card?
