My problem: I have only one PCI-E slot, and is occupied by the video card; I have other free PCI slots, but there are many good capture cards that are only PCI-E... Maybe I found a solution:

don't take in account the upper card; the important one is the lower... this was tested into a PC, same model of mine, and worked flawlessy.

Now, my question: is the ATI 750 the same height of the upper model? Looking at many pictures online, it seems so, but I'd like to receive an answer from an actual owner.

Also, if other capture cards will fit, I could consider on of them too.
