Sure.  First, you don't *NEED* an 8-24 GC with a Rocket since the Rocket
provides not only general CPU acceleration, but also QuickDraw acceleration
using NuBus Block Transfer (just like the GC and also like the original
NuBus graphics accelerator, the Radius QuickColor board).  So, save your
money and just get the Apple 8-24, or better yet the Radius DirectColor/GX
board (since it's probably cheaper than the 8-24).  :-)

As an alternative, if you still need more power in your IIcx, you can get a
drop-in replacement for the stock Apple power supply from several companies,
including Micronet.  You can reach them at (714) 581-1540.  I don't know what
their power supply sells for, and I have no relation to Micronet, other than
the fact that I've seen their power supply, and it seems to be a pretty good
match for a system with a Rocket, 24-bit video, and yet another board.  It
should supply more than enough power for you, but contact Micronet for more
information as to just how much power it will supply.

}thanks in advance,

No problem...
