Understood.  Unfortunately some organizations have no long term vision.

Keep in mind though that going from FE to GE may not actually buy you
any performance as there may be processing or graphics subsystem
bottlenecks that are more of a limitation than bandwidth.

Best bet may be to try one with an onboard NIC and see if it works OK.
If not, buy a GE NIC and see if anything improves.
