I'm running a gtx550 ti and integrated graphics on my machine. My bios has a setting to keep the onboard video running with the external video but keeping the gtx as primary. I have a vga monitor on both cards and an HDMI connection on the gtx. It works great.
For gaming I use softTH which renders a triple width frame using the gtx and then splits it over all 3 monitors.
Hi, quick question: What motherboard are you using? I have a gtx 550 ti also and integrated graphics on my motherboard, but I can seem to get them both working simutaneously. Im in BIOS and I can only choose integrated, pci or pci-e, but not both. Im assuming this is a motherboard thing and I'll have to get another one.
