I ran a 2386 overclocked for many years back in the day. the cpu was heatsinked(and most other warm chips) and overclocked with a different oscillator(i think i pushed my 25mhz board to 33?)and using a diamond speedstar(or was it stealth?) video card allows the isa bus to run near double speed. ram access on the old bridgeboard was not too bad for the time.It actually ran win95 somewhat useable,the 2386 had the capability to use the amiga's floppy and cdrom shared which was handy. there were many 386_>486 upgrades to bring it to a 486/50mhz system.A prog off aminet called amems152(amigaEMS update) would allow you to steal amiga side ram for the bridgeboard.Using SXSERV16 from aminet(must use a gfx card) was much better software than the original Janus.the system actually had better benchmarks that a comparable real 486 the same speed.many years ago there was a company that offered soldering on a new ti486slc50 chip to upgrade the 2386 to a 486sx.
They used to tell me windows 98 would not run on the 2386,but i also managed to get it to run,but it was slow and useless,but DOES work. bbguide.lha and such are good things to read.
Oh yea, PCtask is not that usefull imho and sorry no spare A2386 ;)

Or does PC Task do just as well of a job?
