Closest geforce card in terms of raw power is a GTS 450, it would seem the quadro 4000 is a severely cut down GTX 480. I dont know if anyone runs a card like that but id assume its pretty terrible for mining. Workstation cards are already a poor choice in general due to marginal cooling and underclocked cores/memory in comparison to their geforce/radeon counterparts.
What do you mean by "buy this card at work"? This card is trash compared to pretty much any modern card and no one in their right mind would purchase one.
It is the k4000, sry for my mistake. Cooling seems to be bad either but it look like a good card for calculations.
