Depends what you want. Todays games are awesome in general, but you might not need DP if your frame rate and res don't warrant it. I've been gaming on a 3440 x 1440 ultrawide with a 1080 GTX, and it's been fine with HDMI. However, I want to use my HP Reverb which is DP only, and the GTX does it, but doesn't have the oomph to get playable at effectively 4k in VR. If not for the VR, I'd stick quite happily with HDMI and the GTX. Just as well, as a 3080 seems like it's quite literally years away, despite a 4 month wait already. Have to say though, if you don't have a capable GPU now, I don't envy you - if my recent purchase had actually worked, my used GTX would sell on an auction site for £50 more than I paid after nearly 3 years use!!
