I have a GTX 750 ti (Windforce OC version, Gigabyte) and a GT 730 (DDR3 700mHz version, EVGA) and I was wondering if I could get the cards to work together. I have 1 x16 PCIe connection on my motherboard, and 1 x1 PCIe connection. I know extenders exist for x1 PCIe connectors, but do they work with graphics cards? Thank you
