Hello I'm preparing to get a new little gaming PC, with Asus Z87-A, i5 4670k, Asus GTX760 etc. and I have a question: can I use my old Gigabyte nVidia 9400GT (1Gb DDR2) with the GTX 760 to record gameplays, like a recording card, in order to do not overload the 760? Or is this stupid/unnecessary? Thanks for helping me!
