Currently, I have a Samsung 46 inch 1080p LED as my monitor. My current video card is GeForce 8800GTS: http://www.newegg.com/Product/Produc...82E16814143119

My video card connects fine through the DVI port.

My wife is planning to buy a LG 42 inch 4K UHD for my birthday. I believe this TV has a refresh rate of 240hz. This means that I will need to get a new video card to be able to display 4K resolution.

I read that regular HDMI will not support 4K. A video card with HDMI 2.0 port and HDMI 2.0 cable are a must. Anything else? What should I be looking for in this new video card to display 4K resolution?
