Intel 440EX was similar to 440LX. If you are talking about ATi 8MB card, then it is probably Rage Pro / Rage XL or Rage128 8MB. I think Rage128Pro was 16-32MB.

If you dont want 8MB and it can be more, then take Rage128Pro 16MB, it was ATi low budget card from 1999.

low budget 1999 would be 440LX or Intel 810 or VIA. Intel 810 is unlikely if you had actual discrete video card.

surprisingly yes 😮 https://www.youtube.com/watch?v=3USSO836998 albeit closer to 20 fps on Celeron

It cant be Rage2C, it would be very low framerate if it even starts with RageII and Need For Speed Porche Unleashed.
Here another Rage Mobility 8MB (CR216S): https://www.vgamuseum.info/index.php/cpu/item … rage-mobility-p

A competent low budget build with ATI graphics would be LX, after BX came out no one wanted LX motherboards and the manufacturers used the leftover LX chips on Celeron socket 370 designs.
BX/ZX maybe but those were mostly Slot 1. Did ZX66 exist anywhere other than in Intel's datasheets?
Less good would be a 691/693 Apollo but I'd rather not. Perhaps a quality 693A board but nothing earlier. 694 isgood but those came out later.

i810 with PCI video is possibile but makes no sense.

Graphics card would probably be some flavour of Rage Pro from a random taiwanese company. If you're lucky maybe even one of those with Mobility chips for extra driver fun.

A good replacement could be a OEM Rage 128 from a name brand prebuilt (say Vectra, Optiplex, Deskpro...). They are almost always cut-down designs with a 64 bit memory bus, but have very good output quality and still slighly faster than a good Rage Pro.

There were also several LX/BX/ZX motherboards, both 370 and slot 1, that have an onboard 8 MB Rage Pro AGP, and competent sound aswell (usually Soundblaster PCI or ESS Solo or Maestro). This could also be a neat turn-key solution, and as they lack an AGP slot I can't imagine they could be too expensive.
