Well, no, you don't need a pci express 2.0 mobo to run a pci express 2.0 card. The problem with running the pce express 2.0 card is that it will run at pci express 1.0 speed which is slower than 2.0. However the performance difference between a 2.0 mobo and a 1.0 mobo is very little unless you use multiple video cards. Then the difference will be greater. In fact, you may not even be able to run triple or quad sli or crossfire with 1.0 slots. Two cards will probably work but performance will be noticeabley less than using a 2.0 mobo.
