Riser card for NI 6520 / alternate PCIe cards

Hi,

I am trying to find if riser card like the following works with NI 6520?. Does the usual NI DAQmx drivers support this or do we need any special driver package?

As the newer generation computers comes with less PCI slots or no PCI slots, I am trying to see if one of these riser cards would work. Has any one had experience with using the riser cards. I am trying to check if it works before ordering a riser card. I am open to suggestions on alternate replacement PCIe cards if available. 

Thanks in advance for your help.
