I personally found that the speed increase wasn't as important as the
ease of coding graphics is 32-bit vs. 16-bit. If you're planning on
dealing with SVGA in any way, take my word for it it's just not worth
coding it up in 16-bit! ;-)
If you're planning on implementing a ModeX application, you can avoid
the 64K problem by storing your sprites and video buffers in a 4-plane
memory format similar to the format used by the video card. All in all
though, I'm glad I've taken my company to 32-bit. Even the ModeX stuff
is easier to code in 32-bit, and for the SVGA stuff blits have been
reduced from complicated XMS stuff to sucessive "memcpy()"s.
Hope that helps,
