I dunno about the cx, but the ASTECs were crap in the IIci. My IIci NetBSD server went bananas randomly until I replaced it, and only the GE PSes could stand up to the power demands it needed. The GE cx power supplies should be the same as the ci. I stockpile them for this reason.
Be very careful with the 8*24*GC in A/UX. Do NOT attempt to enable acceleration in A/UX System 7.0; it won't work (and may prevent you from entering the Finder -- don't ask me how I know this). There are very few cards that will work accelerated in A/UX and frankly if you just need 24-bit video you might as well get a much less expensive regular 8*24 if you don't plan to use the machine in regular MacOS, because that's all the 8*24*GC will act as without the accelerator CDEV. OTOH, if you plan to "multi-boot" it then it's a good choice and a very fast card for that class of machine.
My multi-boot IIci has a 8*24*GC card (only accelerated under System 7.1, not under A/UX), a VideoSpigot, and a Farallon EtherWave NuBus card. I haven't tried the Spigot in A/UX, but I would be very surprised if it worked. The NuBus works fine in both systems, though I did need to rebuild the kernel. It also has a DayStar 50MHz '030 with '882, and the Power Central CDEV does work in A/UX, which is very nice. My Presto 040 does NOT work.
