GEIP is based on VIP2-50, GEIP+ on VIP4-80.. so the + is more
performant, has ECC memory, boils mainly down to the differences between
2-50 and 4-80.

Only if you anticipate the 256MB DRAM is not enough.. ECC DRAM in RSP8
is also a +, but you will probably not need to worry about CPU speed..

make sure you'll upgrade to 128 MB DRAM..

depends on the requirements and the budget.. If you were previously
RSP-switching, my guess is that dCEF will give you enough performance
gain for the short future..
