I have the exact same mobo with exact same cpu, it's allright! Not sure about cache though. Says I have 256kb when it posts. Should probably do some tests.

Sound Blaster Pro 2 is indeed an absolute winner for a 1992 build, but for this build it looks more like it's targeting 1993-1994. Despite the fact 486 was released in 1992 it was way too expensive and not affordable at all.
I built myself a 386 with SB Pro 2 and a 486 DX2-66 with SB16 and anything from 1992 I throw at my 386 works beautifully. In 1993 Doom came out and it no longer works on 386, but majority of other 1993 games (I know of) do work fine.
SB16 is a really good choice for 486 since it came out in 1993 when 486 became affordable enough for home market and 386 was a wide spread standard already and many games started to include SB16 in their game options. In addition to that SB16 was released in a combo with a cd-rom and 1993 is a year when cd multimedia craze started to kick in.
Awe32 is a 1994 card, but not for MS-DOS only, as you need at least Win 3.1 to play with sound fonts, so you will miss out if you put it in a ms-dos only machine.
Unfortunately I don't know much about non-Creative cards history.
