This era was fun to overclock =) Can you give some info on the motherboard, like make and model? Also if you can get a picture of the 486 that would help immensely. There were so many different ones, made by different companies ... which is what made the era great =)
If the motherboard supports 40fsb, which would be a jumper, you have a fair chance to run that chip at 80. Also in this modern age you can apply exotic cooling techniques such as... using thermal paste =D
Since the system is already running a DX2, the board should already be 3.45v compliant, and there's a good chance you can run an AMD 5x86 in there. Look for something like 5x86-P75 on ebay or around. They're basically just 486 with x4 muliplier. Stock is 133Mhz, but almost all will run 160 (40x4).
Also check the forums http://www.vogons.org/ since they specialize in old hardware.
But last, have fun with it. These old systems are a hoot. And if for whatever reason you tire of it and want to junk it offer it here, because finding old stuff still complete is hard and as you've already noticed, people want these.
EDIT: Also to add, a DX2-66 is more than happy to run win95. The huge part is having enough memory though... you really want at least 8Mb, more is better. Win98 will want more, but it's not excessively more. Finding 30/32 pin SIMMs is kinda hard now though (EDO or FastPage)... but some later boards took SDRAM (the generation right before DDR1) which is also why it's so important to know what motherboard you have.
But again if it already supports a DX2, it's at least later generation 486. It's interesting that it's "just ISA" ... are the slots brown by chance? There is a chance it's EISA. Or maybe there are some VLB (Vesa Local Bus) slots there. Hehe, so much variation those days, kinda miss that now.
Socket 5/7 is like that too, so if you get to that retro box let us know - Super 7 motherboards in particular were awesome fun for abusing stuff in. But that's another thread. (setting my EDO 72pin SIMMs to 112mhz? ... that corrupted POST screen was priceless lol)
