Also, it depends on what you intend to do with it and what OS you
intend to run. In particular, as far as I can tell the hardware that
supports what acceleration the cg14 has is undocumented, meaning an
open-source OS will be stuck with dumb-frame-buffer levels of
If you are satisfied with 8-bit PseudoColor but want acceleration,
you're possibly better off with a cgsix in an SBus slot - a higher-end
cgsix, if you want more than 1152x900 (or, more precisely, more than
1<<20 pixels). (The 4M VSIMMs are cheap but limit you to 1<<20 pixels
unless you're willing to live with 8-bit PseudoColor; the 8M VSIMMs
lift that limit to 2<<20 pixels, but are significantly more expensive
in my admittedly limited experience.)
And, yes, a VSIMM will lose you one RAM socket.
Personally - ie, this may or may not be useful as a guide for you - I
run NetBSD and use VSIMMs; I have very few cgsixes with more than a meg
of VRAM and am mostly willing to tolerate 8-bit PseudoColor. I have a
few 8M VSIMMs for the cases where I do want good colour. And, for my
workloads, a couple hundred megs of RAM is ridiculously over-specced
anyway, so I don't miss the RAM the VSIMM prevents me from having.

Or, if your uplink is slow enough it can't max out 10Mb, you could use
the onboard le for the uplink side.

Well, don't forget, performance isn't necessarily the goodness metric
here. If it is, an SS20 is a bad choice for just about anything.
