VGX Upgrades

Warning on the Purchase of VGX Upgrades:

     When the VGX upgrade to the GTX system was announced, I asked
my salesman for a quote and some information on that upgrade.
He stated to me at that time that the upgrade was for "any
GTX" system. In fact, the quote I received from him states

     "Upgrade from GTX graphics to PowerVision graphics".

     Last week the VGX upgrade rolled in. It is scheduled
for installation on our 4D/120 GTX system. 

     The salesman called me last night to say that VGX upgrades
do not work on 120 GTX systems. He says that we have to
upgrade the 120 GTX to a 220 GTX system (and he sent a
quote for about $20K).

     What's wrong with this picture? Is there anyone at
SGI able to field such questions?
