Beware that several people have reported some rather strange problems with the Highpoint cards.

I ordered one from a while ago, but the shop went bankrupt before I got it, or at least their web site disappeared and they stopped answering mail or phone calls. >> > In case I have to replace my Silicon Image card, what should I replace >> > it with?
