My first PC was an IBM PS/2 80 (until that point I stoically stuck with my Commodore 64 way past the point where it was remotely viable), and it came with no sound card, so my first upgrade was the unfortunately extremely expensive sound card that used the proprietary expansion slot on that series of computers (MCA I think).
HELL YES it was worth it, the card I got was 100% soundblaster compatible, and going from PC speaker to that was completely amazing. I then went on a shopping spree and picked up Ultima 6 and 7, Quest for Glory 3, and Legend of Kyrandia, and was in Adlib/Sound Blaster heaven. The Legend of Kyrandia, by the way, has one of the greatest Adlib soundtracks of all time (though the MT-32 version is killer). Between the beautiful VGA graphics and the amazing soundtrack, Kyrandia is the first game I played where I really felt that I was justified in finally retiring my C64 and moving on to the IBM PC/compatible world (in terms of gaming, I mean).
[EDIT] I was always curious about the "ROLAND MT-32" and "SOUND CANVAS" options when setting up my sound card for games, and only a few years ago I managed to get my hands on both an MT-32 and SC-88 (later, an SC-55), both of which work fine with DOSBOX. I can only imagine how I would have reacted to these devices back in the day, when they were hundreds of dollars PLUS you needed to buy an interface card just to get them to work with your computer. These things are simply amazing, and it's quite a trip to play EGA games like Quest for Glory and Space Quest 3 with near CD quality music playing in the background on an MT-32. It's also mind blowing to find out that the redbook audio soundtrack for the CD version of Warcraft 2 is basically just MIDI music recorded off of a Sound Canva (likewise, the music that plays during the FMV intro to System Shock is just recorded straight from a Sound Cavas).
