hey, i use 2 zotac ion's and even the n230 version, it's working great, even with 1080p because of vdpau.
So in my opinion you can't go bad with either one, but the zotac is probably more plug and play.
Remember that you will probably get a black screen for the AVWizard and need to use the number or q key to get into the AVWizard. If you want to use hdmi sound, make sure you unmute the channels in alsamixer.
I choose the n230 because it had passive cooling, and i didn't want any noise coming from these md's
As far as i know the 330 needs a fan, the 525 i don't really know
