The graphics were not 10 years ahead, not even 3 years. First SVGA cards came out in 1987, with a 320x200 in 256 color mode that was far more practical than Amiga's 4096 color mode, and with resolutions of up to 800x600. By 1995, resolutions of 1280x1024 with 256 colors were widely available, and Nvidia released their first graphics accelerator.
The first SoundBlaster cards came out in the late 80s. The SoundBlaster 32 released in 1995 was far superior to the Amiga.
And the state-of-the-art CPU in 1995 was the Pentium 133, faster than a 7Mhz 68k by orders of magnitude.
The Amiga 1000 was an awesome computer. But technically obsolete by 1990.
