question on mutliple sound cards and world clock

ok, in brief im running on a M audio delta 1010LT card, and now ive got my hands on a second card which i want to install, apart from pc tower itself i don't use any digital or midi hardware in set up, so when i install second card would it be a case of plug and play (apart from some fine tunning settting up etc) or would i still have to sync world clocks between cards?? card already installed is set to using internal world clock ..where ever that may be lol



any advice before i install and ruin my weekend? hittt
