Well then, I have some questions:
What OS does support dual CPUs?
What can a Dual Voodoo 2 setup handle?

NT 3.51, 4.0, 2000, and XP.
None of those OS will play well with voodoo 2's.

I have been planning something similar for a long time now, everything is at hand, I just need time and passion to assemble the rig:

Pentium III-800 (only 100MHz FSB for now, I'm looking forward to get a 133MHz model, but we'll see how this one overclocks)
ASUS P3V4X
4x256MB PC-133 SDRAM
GeForce Ti4200 128Mb
2x 3dfx Voodoo2 12Mb
Creative SB Live! or Aureal Vortex SQ2500
Creative SB 32 CT3670 or some SB16 thingy.

This won't be my first build. I will first do a Super Socket 7 PC. That was inspired by PhilsComputerLab. It follows his "4-in-1" PC video. Then, I will be able to play every era of Microsoft gaming. The Slot 1 PC will come later.

very good, but win98 sometimes has problems with more than 512mb of ram. if you have issues, drop down to 512mb and try again.

if you TRUELY want to dive into the deep end of slot 1 dual cpu boards: http://www.ebay.com/itm/121942662629

Holy cows... That is INSANE!

Yup, good point.

Don't listen to luckybob, he'll drive you mad. Next time you know, you're in a room full of server gear running a 32-core xeon to read the forums 🤣

You should see my garage... ^.^

but seriously STAY AWAY from dual cpu boards if you plan on playing games pre-xp. Its expensive, and not worth the extra money, time and effort. That said, I'm a masochist and I love dual CPU systems.

Build a basic system, THEN "upgrade".

Yeah. I'll start with the Super Socket 7 PC, then work my way to the Dual Slot 1. So the Dual Slot 1 could run XP?

No problem. Once you start using 2000 or xp, you can cram as much ram into the system as you want. And those systems like ram.

Cool! Thanks for all the info guys! It really helps!

Same advice on SS7 boards. Stick with the name brands. I have several Asus P5A boards and all are wonderful to use, but pricey.

Right. I have a separate thread about my Super Socket 7 build here. I'd love some more advice there, since that will be my first build.

If you want "the fastest" Slot 1 motherboard than look at something with i840:

I have one of the intel i840 boards. VERY nice board, but the hassle of RD ram with this chipset really turns me off.

If you decide you REALLY want to throw your weight around, ditch that sissy-mode slot 1 and go for slot 2.

Behold the UNOBTANIUM Asus XG-DLS with 2gb ram and 2x 900mhz cpu with 2mb cache each:

No its not for sale, at any price.

My Win98 Retropc is built around an Asus P3V4X and I'm very happy with it. 😀

Fixed your post. 😀

(in my defense, I am currently contemplating a dual LGA1366 build myself)

Oh, then you have to think, how do you want to have the IOH (5520 chipset) attached. On many motherboards there are 2 of them, but EVGA has only one and nVidia PCIe bridges on their SR-2 and it helps in some very specific circumstances (multi GPU setups). Thread derailed 🤣

5520 - this build will be primarily a game server. No fancy VGA required. I'm eyeing a cheapish HP server board on ebay. Have the CPUs (2xL5520), memory and PSU, need coolers.
