DVI -->HDMI vs. Thunderbolt monitor question

So I ordered a Dell U2913WM Ultrawide monitor for my Mac Pro and Pro Tools 11HD setup. I now realize that I may have to settle with the DVI to HDMI connection from the Mac Pro to the monitor. I can refuse the delivery and cancel my order and spend more dollars getting an ultrawide monitor that has built in thunderbolt ports, (LG 34" ultrawide).



My question is....would there be a big advantage going with the thunderbolt connections to the monitor or is the DVI to HDMI connection sufficient to use Pro Tools or should I spend the extra dollars to get the thunderbolt setup?



Thanks in advance for the advice.
