Is the Quadro worth it?

building a new server,
i have had a mother board fail. took some other things with it.

my question is are the high end gammer cards fine,
or should i just buy a new Quadro?

I normally use Quadros as there are models, that only uses a single slot, instead of the big dual slot beasts. But if you have the room in your case, it should also work well.
