Hi,

I have ASUS M2NVM-HDMI motherboard, you get the specification about this motherboard from web. This mobo has PCI-E slot, but it is not PCI-E 2.0. So if I use a graphics card which is for PCI-E 2.0, will it work in my mobo perfectly?

In theory yes, however history has repeatedly shown that practice may be a different matter for the first batch of v2 cards. See Q3-5 of PCI-E 2.0 FAQ (http://www.pcisig.com/news_room/faqs/pcie2.0_faq/).
