Carol: he isn't gaming, so he doesn't need the GPU power (or power consumption
) of dual cards in crossfire.
I'm personally not too keen on ATI/AMD GPUs because their drivers have behaved
very naughty (BSODs
with data loss) when using the LargeSystemCache=1 setting. Nvidia drivers kinda suck these days too, the last couple I've tried have given boot-time BSODs, so I'm using older versions.
Matrox cards are way too expensive to even consider, imho. What about the ASUS EAH3650 SILENT/HTDI/512M? Looks like reasonable price, and has two DVI outputs (and can even do HDMI with audio via a DVI->HDMI converter). And it's passively cooled, meaning less noise... haven't checked reviews or benchmarks on the card, it was just what I found from "passively cooled, 2xDVI, reasonable price" criteria
