[SunRescue] Creator 2D/PCI card in Ultra 5?

[nick at ns.snowman.net]

Close, but not quite.  AGP 4x is 133mhz, and it's double pumped (I think
it's 4x, may be 8x) but still only 64bit.  And it's not the card that
inherantly sucks down the resources, it's the app.  A true gfx accel. in
agp or pci form will only take more resources in agp form IF it needs
them.  Doing the same ammount of work will transfer ~ the same ammount of
data over either buss, but the agp one will finish first.  If you're in an
app where you Can't finish first then agp will do more work, which will
translate (usually) to better gfx, and more system hogging.  If you have a
link to an agp scsi card i'd love to see it.  The prob is you'd need a
mostly new driver for it in winblows (it'd work with a minor tweak, if any
in linux).
