Sorry to double post myself, but I don't seem able to edit my post!
I know that there are different types of DVI:
DVI-I = digital + analog (can be converted to VGA)
DVI-D = digital (can't be converted to VGA
DVI-A = analog only
What I want to know is - if a card just says "DVI out", like the 7900GS I linked above - which DVI type is that likely to be? Or will it vary from card to card meaning I need to make specific enquiries about each card before I buy?
Since I can't use DVI-D, I don't want to buy a card hoping it will be DVI-i (or DVI-A) only to find it's not and I have to buy again!
