4K question

[5960xNvidiaGamer]

Hi guys, I have been speaking to a friend and he informed me that when 4k is at 120/144 hertz I will have to upgrade my 980ti as it won't be compatible. Is this true? what connection will 4k use at that hertz? I thought it would be the same as it is now.

might be stating the obvious but a single 980ti won't be playing any current or future titles at the framerates that will take advantage of those refresh rates in 4k....

Yeah I know that, I just wanted to know if it will be compatable, I will get another 980ti or 2 if they are.
