As your new I'll give a detailed answer.
There is very little difference between the AWE sound cards, especially for gaming.
Awe32 is basically a SB16 with the EMU8000 chip. Pros may have Yamaha OPL chip, standard 30 pin Ram, Cons Hanging note bug, nosier
AWE64 is basically the same as a AWE32, the other 32 voices are software only. Pros less noise, No hanging not bug, Cons CQM chip, Non standard RAM
AWE64 Gold is exactly the same as standard AWE64 just less noise
SoundBlaster 32 Same as a Awe32 but based on a Viba16 rather then SoundBlaster 16 (No Echo/Reverb)
Finally you have the the CT192x Goldfinch add on boards, which is the "AWE32" part missing to SoundBlaster, but these things are rare.
CT1920 AWE32 Upgrade, Music volume
Really IMHO the AWE Golds are overhyped anyway.
