I agree with you whole heartedly, but I don't want to build this machine solely to play games on, at least not entirely games. I always thought the VLB bus was cool, and would just like to reuse my original cards in a machine to fire up from time to time and poke about, nostalgia, memories, maybe use as a win/unix terminal, front end for basic stuff, even productivity related stuffs! I have a single DX66 with a pretty heatsink which needs a home in something, so I figured one more 486 could never hurt... much...I hope! At either rate, I only have a very middle of the road ATI Mach32 1meg card, and some memory to try out to make it 2 meg I hope [further research needed here as to what chips are supported!] , so it won't win any awards here! I am patient when it comes to this, there is no rush, its just an idea...
I have our family's first computer 486 from 92, DX50 on a Seanix SB-SYM-486C which has the " ATI VGA Wonder XL24 " with a bus mouse, I use for testing out old hardware on a bench setup, occasionally toms rtbt poking about, but it isn't really capable of running any games like duke3d et el ... For that I agree with you a socket5/7 mmx or even P2 is the sweet spot, I have one with a motherboard that needs sometime to fix the VRM setup properly so it doesn't cook itself any further.
