I dont know if you care to spend the money, but the Awe64 does have a tad better sound quality then the AWE32. Up here in my room I have that Gateway 2000 tower that uses a Awe32 and a Pentium 100mhz cpu and a Dos install. I think the graphics card is a S3 or Matrox Pci card, don't remember which. If all you planned to run is Dos games a straight Dos install might suit you better then Windows 95, but I don't know what all you plan to run. My other Dos system is a dual boot Dos/Windows 98 build. Specs are:
AMD K6-III @ 400 mhz
Epox SS7 motherboard EP-MPV3G2
AWE64 soundcard
3DFX Banshee AGP
256 megs ram
two Quantum Fireball hard drives (one for Dos, one for Win98)
DVD drive
350 watt psu
Chen Ming ATX-103B case modified (perfect cut) to have a air intake area at the top for a 80mm fan
Most of my Dos gaming is really handled by this system, since its basically fast enough to handle all the later more demanding Dos titles like Quake or Chasm: The Rift just fine. Really though I have a lot of decent boxes in my parts storage area, like a complete Packard Bell Pentium 150 tower. Also have a few empty AT cases, probably about 25 different ISA sound cards, normal cases, motherboards, etc. The only stuff I don't have is old 486 and prior, as I wont use anything slower then a Pentium 1, and most 486 and prior I come across the motherboards are ruined from leaky batteries.
EDIT: here is the info on my large Pentium 100 Gateway tower.
Pentium 100mhz
S3Trio64 Pci
Creative Awe 32
Seagate 1.2 gb harddrive
plain jane cd-rom drive
64 megs ram
150 watt psu (I think???)
(shot of lower area of the inside, since I needed to pop it open and do some work on it, swapping out case fans, etc)
