Well, in my even more humble opinion:)

Even newer computers videomemory is rather much slower than the
processor(even if their memory exceeds the computer memory in speed),
ex:

on my amd300 a loop wich moves bytes or an inline rep stosl
that transfers information from memory to videomemory is
equally fast.

And, on older gr-cards bank modes might be faster because
it's hardware implemented(and no software workarounds) and
the other way around, fornewer cards. Thats the most
important, not a houndred clockcycles to switch bank.

I'm always trying to move as little data as possible, ram->ram and
worse ram->videoram.

This is only what I belive:)
