Will I need another graphics card to support higher screen resolution of 2560* 1440. I was told I need a graphics card which has a display port. I thinking of getting another monitor which has a display port. A Dell 27" 2717D. Current monitor is connected by HDMI with only a 1080p resolution.
Which graphics card will be compatible with my motherboard - will this graphics card be good enough - Sapphire AMD RX 460 2GB OC Dual Fan Video Card
Current graphics card: ATI Radeon 5450
CPU - Asus M5A78L-M/USB3
Yes, the RX 460 will support that resolution provided you have a power supply unit that meets the cards requirements,.
