I can buy tomorrow a Pentium 2 266mhz with 128mb for 40$. But i dont think its enough strong to play Glide games in 1024x768 with high details at 60 fps like NFS III , NFS IV and Porsche unleashed, Tomb Raiders series, Ultima 8 and several others games of that time. What do you think ? Is it it enough for 60 FPS in most games in 1024x768 ? Maybe i could buy the P2 266mhz and the P3 too.
Is it ANY advantage to have a Pentium 2 266mhz vs Pentium 3 at 500-600mhz for DOS GAMES?
Definitely not worth it. A Pentium 2 266, while it will be faster than a Pentium MMX, it will still be a severe bottleneck for later Windows 98 games. And as for DOS... yeah, it will be better for later DOS games, but not MUCH better than a Pentium MMX 233. Also, the P2 doesn't have the same slowdown capabilities that the Pentium MMX does. And if it's based on the 350nm Klamath core, it's quite power hungry and runs pretty hot (especially for such a slow CPU).
My suggestion is to keep the Pentium MMX for early DOS & Windows 95 gaming, and buy something much more powerful for late Windows 98 games/late DOS games.
When it comes to achieving 60 FPS, things get a bit tricky:
- on the one hand, Tomb Raider games up to Tomb Raider 5 "Chronicles" are capped at 30 FPS and should run without frame drops on a Voodoo 3 2000/3000 and a Pentium 2 450 (maybe even lower?).
- for games such as Need For Speed Porsche, you absolutely want a video card capable of 32 bit color and high resolution 2048 x 2048 textures (this game looks washed out on Voodoo cards prior to Voodoo 4/5). And even though the official system requirements are quite low for this game, if you want high resolutions and a perfectly smooth 60 FPS without frame drops, you really need to go with a powerful GeForce/Radeon card and a pretty fast CPU. I usually just play this game at 1600 x 1200 on Athlon XP / Athlon 64 / Pentium 4 / Core 2 Duo, paired with a video card such as the GeForce FX 5900/Radeon 9800 series. At 1280 x 1024, if I remember correctly, even a GeForce 4 Ti 4200 is able to achieve 60 FPS (with very few frame drops). But the general idea is that this game is more suitable for a more modern (but still retro) rig 😀
Again, if you want my suggestion, keep the Pentium MMX for DOS / Windows 95 gaming, and buy a very powerful (but flexible) system for anything else.
My recommendation for a super flexible "time machine" system, is a cheap Athlon XP Thoroughbred (such as this Athlon XP 1700+), paired with a VIA KT600 / VT 8237 motherboard like this one.
Such a system has many advantages:
- The CPU has an unlocked multiplier: it can go as low as 500 MHz (with 100 MHz FSB / 5x multiplier) or as high as 2 GHz + (at 166MHz & 12.5x multiplier), most of these chips needing just a small voltage bump for these high frequencies.
- The Asus A7V600 motherboard (unlike other KT600 motherboards), has all the bells and whistles for overclocking / throttling the CPU. You can disable either the L1 cache, the L2 cache, or both of them.
- The VIA south bridge is extremely compatible when it comes to DOS: Sound blaster digital speech will work perfectly with many sound cards and it also supports even further granular hardware throttling with the Throttle application. Add a Yamaha YMF724/744 or ESS Solo-1 sound card, and you're good to go.
- As for the video card, you can first get a cheap GeForce 4 MX 440 (which, don't get me wrong, is still a VERY powerful card, probably more than twice as fast as a Voodoo 5 5500). This card is a great performer in Windows 98 and very compatible with DOS games.
A system like the one above is probably the ultimate time machine PC that you could build. It can be tuned down to 386 speeds, 486 speeds, Pentium MMX speed.... all the way up to Pentium 4 equivalent speeds. So you can cover 15 years of gaming. 😀 For many people, such a system would be enough - there would be no need to buy any other retro parts 😀 Unfortunately, I'm crazy, so I can't just settle with one system for everything 😁
Now, the catch is that, if you want to also overclock the CPU past 1.8/1.9 GHz, you will need a PSU that has a pretty beefy 5V rail (at least 24 amps), since most socket A motherboards draw a big chunk of their current from the 5V rail. Such PSUs are harder to find nowadays and they are usually quite expensive.
So the alternative would be to go with an Athlon 64 socket 939/754 system (with a VIA K8T800 / VT8237 chipset) which can also be used as a time machine (it can also be throttled down to 386 speeds using hardware based throttling, not emulation), but it's not as ultra-flexible as the Athlon XP system described above. However, the advantage is that you can use a modern PSU with it and, of course, it's faster and more efficient compared to Athlon XP.

About overclocking the Voodoo 3 2000 PCI.. Is it any risk to overclock it at 166mhz core and 166mhz for ram like a voodoo 3 3000? I will add a fan on the core heatsink. But i dont know if i should add heatsink for memory ? If you think any risk exist in overclocking it at 166mhz for core and memory, i wont do it. I think of using Powerstrip. If it safe and stable i can always update the bios to the Voodoo 3 3000 pci version, but it surely risky.
In 2002 i burned a geforce 256 with overclocking. i was very sad. But for punishing me my parents bought me a Geforce 2 GTS 😉 LoL! i never overclocked it LoL!
There's no point in overclocking it. The Voodoo 3 2000 is quite powerful and it will work great with any Glide game, being able to achieve more than 60 FPS with the right CPU. And for later Direct3D games that don't work well with it, you might as well just go with a GeForce/Radeon card, overclocking the Voodoo 3 won't help. Very important thing to note: make sure that the card is extremely well ventilated (especially the MOSFET on the edge of the card, which gets VERY hot, even hotter than the chip itself). Whenever I use my Voodoo 3 PCI cards, I always add a large 120 mm fan that cools both the chip and that problematic MOSFET.

About slowing down my P233 mmx like a 386 and 486. Is it any better way than disable L2 Cache or using utilities ? ( i know 2 utilities to do it) and i can change board jumpers to get it at 75mhz.
Setmul is the way to go with a Pentium MMX. For 386 speed, however, you will also need to disable the motherboard (external) cache. I think you should watch Phil's video, he explains things quite well: https://www.youtube.com/watch?v=F8s0H5_-SRU

Thanks again for the time you take to answer my questions. Its really appreciated it a lot. Special thanks to Bloodem, you pretty much answered all my questions since the beginning of my topics. 😀 But thanks to you ALL guys ! Its a new hobby to me playing with old hardware 😀
You are very welcome. 😀

And is The Yamaha sound card use any sb emulation processing power like a sblive ? if i have the sb link connector does i avoid sb emulation "processing power " ? So DDMA is not a sb emulation, but only if i have to use DSDMA ?
The Yamaha card does not use any emulation, it does everything in hardware and it has a REAL Yamaha OPL3 chip - so FM music will sound perfectly (unlike the SB Live that you mentioned, which does use emulation for everything, and its FM sound is just... trash). DDMA has nothing to do with the card itself, it's a feature that is either supported by the motherboard chipset or it isn't. If it isn't, you need to emulate this feature with a TSR such as DSDMA, but this does not mean that the sound card will use emulation for playing back FM music / digital speech - these will still be hardware based. You can read more about SB-Link/PC-PCI and DDMA in this official Intel document.
