Benefit of DMAC04 in A3000

[desantii]

I recently upgraded my A3000 with a Buster 11 and a DMAC04, is there any benefit of the DMAC04?
Currently it is working fine but I had read that you need Ramsey7 to work with DMAC4, mine works fine with Ramsey 4
 
Any benefit of Ramset 7? or should I go back to DMAC2
 
thanks

Tempting to sell my DMAC 04 as it is sitting in a stock A3000 an 040 for the 3000 sounds tempting!
 
I got it from a dead 3000 Tower

I meant an 040 as an upgrade
