Which speeds up a Macintosh IIci's 24-bit graphics more: a cache card or a
Macintosh Display Card 8*24 GC?
By far the best choice for speeding up 24-bit images is the Macintosh
Display Card 8*24 GC. Off-loading the graphics processing from the
central processor speeds up screen imaging and "number crunching" (as
neither is interrupting the other).
