I have a M-Audio Omni Studio (delta 66 SC) .. What do you guys think of this card?

Also, what mic preamp and mic would you recommend for it, i mean is it worth buying gigh tech gear for it, or the card is not worth anything. Besides the mic and pre what other gear would you recommend.. for the mic and pre, i was thinking of the AT 4040 and a FMR RNP and RNC ..
PLease help on anything ..
