[comp.sys.mac.hardware] Graphics accelerators?

I have become frustrated at the slow graphics on my 8-bit color
Mac II system.  My communications program can't keep up the 
scrolling of text coming from my 9600 baud modem when in 8-bit
mode.  I have to wait for complex graphs to be drawn under Excel.

I'm wondering what the cheapest ways are to speed up the graphics
at least 100% (i.e. double the speed).  Will Apple's 24GC card
provide the speedup I'm looking for?  Are there any third party
graphics accelerators?  If I can only get the speedup by upgrading
to a faster 24-bit card, that's ok.  I'd like to stay under $1,000,
but if I also get 24-bit color, $1,500 is ok.

One more quick related question while I'm here.  Are there any boards
that stretch the resolution capabilities of Apple's 13" color monitor
beyond 640x480?  MaxAppleZoom gives me 704x512.  Can I go beyond that
with a different card?

Thanks in advance for any replies, David Bolling (slart@pawl.rpi.edu)
