For a certain type of games sure. We'd all have loved to have UFO Enemy Unknown be less pokey. But there were plenty of areas where CPU power was important: Coding, all sorts of applications (including graphics which was a popular use of the amiga community), and later games.
It'd also permit more advanced games. Look at things like Genetic Species and Onescapee for some simple things that were possible with a decent 030 and AGA.
Better CPU allows better 3D games, better productivity apps and so on but PC world was already having SVGA as a standard and games used it.
After all in mid 90s Amiga was losing its fight on all fronts: 68k CPU arch was dying, AGA couldnt compete against SVGA, the OS development was slow and 4 channel 8-bit audio (Paula) was aging. Even if Commodore did few more things right they didnt have a chance.
And of course all those fancy companies making fancy games for PC...
