I had an AWE32!! Complete pig to install though. ISA cards just wouldn't show in Win 95 and until you went through the faffage of the add new hardware wizard and point it towards the drivers. HUGE card though.
My first sound card [ can't remember what it was now ] - cost me £200 !!
And my first CD Rom drive - cost me almost £300 but it was quad speed.....
I had a Gravis Ultrasound II, a great card (at the time). It had half a meg (!) of wavetable-RAM.
My first CD-Rom drive was a single-speed Mitsumi drive. If you wanted to change the Disk, you pressed at the front of the drive, de complete drive came out and then you could open the cover to change the disk. It cost me what today would be around € 300.-.
Edit: Just found a picture of it:
My first 'decent' soundcard was a Soundblaster 16 - a necessary upgrade in 1993 as the game Syndicate only came with driver support for the SB range. My wife thought I was nuts spending £149 "on that' !? Just to play a game....?".
