May be better: k6-2 with vodoo 1 (dos and w98) and pentium III 1400 with vooodoo 2 sli + geforce 6600 (XP)?
No. A voodoo 1 is more appropriate for an early pentium.
On a K6 you can run games up to 1999 very well. I run GL_Quake @ 1024x768, Quake 2 @ 1280x1024, Half-Life @ 1024x768, Descent 2 and Carmageddon 3dfx at 1024x768, Unreal @ 1024x768, Quake 3 at 1024x768, SHOGO @ 1024x768, Homeworld @ 1024x768 - you get the point. You won't really get that much more performance from a PIII V2 SLi build, since the cards themselves will become a bottleneck - they are WAY more suited for a K6, since there are a few 3dfx DOS games that will act up on faster machines (uprising comes to mind). Speed-wise, a 650-700Mhz P3 or AMD Duron tops out a pair of V2 cards.
For a fast P3 like a 1.4Ghz tualatin it's best to use a Voodoo 3 3000, or Voodoo 4 4500 / Voodoo 5 5500 if you can find one.
Do NOT put anything faster then a GF4 Ti in a pentium 3 machine - you WILL encounter loads of hardware and driver issues. Even FX cards top out at SOME FX5700 cards. Besides, a Geforce 4 Ti is a beast of a card. It ran Black and White @ 1920x1080 on a socket 754 3500+ / Geforce 4 Ti 4200 and it never dips under 28 fps.
I had an FX 5700 in my tualatin rig at one point, but I had lots of issues with older games so I reverted back to a GF4 Ti. Examples: black screen in DK2, texture corruption in Homeworld 1, flashing menu text in SHOGO, hangs in Lego Racer.
Also be aware that newer cards like the GF 6600 and FX 5900XT have a huge AGP power draw - even if they have a dedicated power connector. This causes system instabilities on some motherboards only noticeable in some games and benchmarks. They also have AGP compatibility issues. Some cards (like the 6600) might be keyed for AGP 8x only - as such they won't physically fit a 2x slot. They will also act up in universal AGP slots (4x) that only provide 3.3 or 1.5v (the card requiring 0.8v as per AGP 3.0 spec).
Of course, if you have the time, patience and money you can experiment for yourself - but be warned - mixing and matching generations like this in pursuit of ultimate retro performance will tax your wallet and nerves.
tl;dr - if you want a blazing fast windows 98 rig for silly resolutions and detail levels, build a fast socket a / 478 / 754 / 939 / 775 rig. There's plenty of AGP 754 and 939 boards out there - even some nice i865 LGA775 boards - these have win98 drivers and make for kickass fast win98 rigs.
My "ultra win98 rig" is based on an Athlon 64 3800+ single core / Geforce 6800 AGP and can max out every old game, as well as run Doom 3, Quake 4 and GTA 3 under XP. This kind of build gives you great flexibility. You can also add a Voodoo 2 SLi kit to it for Glide games, although you could just use an emulator for glide (like nGlide) since the CPU is more then fast enough. Here's my build: Win98 Socket 939 Voodoo 2 SLi Build! (a.k.a. Glide Overkill)
