Basic Crossfire question - Follow-up question

[IronWing]

I have a ~5 year old Dell Ultrasharp 20" monitor with a single DVI port and a VGA port. Does Crossfire use a single DVI connector to connect to a monitor?

Yep, only one connection needed.

Thanks. I'm planning my next PC and I don't want to buy a new monitor unless I have to.

Follow-up question: I realized I actually have a 19" monitor (UltraSharp 1905FP) not a 20" model as I was thinking. The max resolution of the monitor is 1280x1024. I'm looking at a passively cooled ATI 5750 card and was considering getting two of them in Crossfire but now I'm thinking that at 1280x1024 I might end up with two underutilized cards instead of just one underutilized card. Eventually I'd like to get a bigger, higher res monitor but I can't justify it while this one still works well. So my question is: Would I see any performance gain at 1280x1024 from crossfire or would the the second card be a waste of money until I have a higher res monitor?

It would pretty much be a waste. Get a single card for that resolution.
