Also, I think Amiga sound can almost hold its own nowadays: the standard Paula chip was still a standard feature, which PCs still don't enjoy nowadays.
Not against MCP-T(APU) Sound Storm (e.g. X-BOX-I and NForce I/II). ALC650 chip (majority** of nForceII boards e.g. ASUS, Gigabyte) has 6 channels @20bit output and EAX1 acceleration. This particular AC97 chip murders Paula anyday.
**Statistics claimed from nForcershq.com’s survey (e.g. ASUS brand is the dominant).
I think that AGA was better than VGA as well.
AGA was proven less desirable in the long run e.g. with arrival of ID's Doom (1992) and Origin(now EA)'s Wing Commander. This is turn spurn other X86 PC games of similar era e.g. Rise of Triad, Indy Car, Mech Warriors 2, Duke Nukem 3D, Dark Forces 1, X-Wing, Decent, Tie-Fighter, DOOM2 and clones of DOOM. During falling prices of I386 clone boxes, Linux and Windows NT was born.
