I find such advice may be well meaning but something must have been lost in translation.
So without going into any discussion about the card compatibility with the PC, the answer to your first question is yes. The final question the answer is no.
I have been told that I must turn off Java script in order to use video with USB 3.I edit video and have added some USB 3 external hard drives and I am getting a Vision tek USB 3 PCIe card so I can have the faster transfer speed. I have been told that I need to get an Adobe product (do not know which application) to subsitute for Java script as it will not work with video on USB 3.I use Win 7 home ultimate,CPU AMD T-1045 Hex core,EVGA GTS 450 gc..Is this true?
