d24 mix upgrade options?

[kboy]

Hi,

current setup :

mix farm
d24
dsp farm
dsp farm

this setup gives me 64 voices with 3 888's connected,

what options do i have in terms of upgrading to either 96 or 128 voices ?

could i add another mix farm card (thereby losing 1 dsp farm as i only have 4 pci slots)
or
swapping the d24 card for a mix core ?

i dont use to many plugins , my priority is max voices with potenial to add more 888's for inserting
outboard gear,

thanks,
