The CPU has an integrated "graphics card" called IGP. The HDMI/VGA ports in the mobo are linked to the IGP, but you'll be using the dedicated GTX 750 Ti, so use it's ports to connect the monitor.

You could still use the 750 Ti through the mobo ports theoretically, since your motherboard supports Lucid Virtu (switches between the IGP and the dedicated GPU based on graphics load: IGP at low loads to save energy, GPU with high loads for maximum performance). But I wouldn't bother. That 750Ti draws next to nothing when idle

Oh ok. So I'll stick with the MSI 750ti 2GB with the HDMI, DVI and VGA ports. Thanks

Awesome, thank you very much for the help! Looks like I'll be getting that setup, with the i5-4670K instead of the 4590S :) 

Why not get the 4690K its the same price but a little faster.
