I currently own an ASRock z87 Pro 4 and I have a GTX 770 on it, along with 2 other capture cards in the PCI slots. I was wondering if the performance of these cards are affected by the motherboard? Say If I was to get an Asus Asus Maximus VI Formula, would the performance of those cards be better? I feel like the motherboard I currently have can't handle all of those 3 cards? Maybe it causes a small clog? Just wondering.
