I bought this to give better performance to my PC. I recently got a 28" 4K monitor and while my old board ran it via HDMI, this board has Display Port output which upped the frame rate. This board also supports 3 monitors so I have more desktop to work with. Would definitely buy again. Bought MSI to match my mother board. According to documentation, you need at least 300W power Supply and PCI-E v3.0
