DVi needed for gaming

[ksungela]

I intend to purchase my first LCD for my home computer. I'm considering the Samsung 910MP which has a built in TV tuner with picture in picture feature which is kinda neet for when I'm working and want to watch the NASCAR race and don't want to miss the crashes. However, it has no DVI input. I also do gaming, so I'm undecided if I should give up the TV within the monitor feature and get a monitor with a DVI input. I've read reviews on the Samsung 915n which also doesn't have a DVI input and users say its great for gaming. So, how important is the DVI interface for gaming?
Thanks in advance for your response,
Ken

I have a vp930b and tried both d-sub and dvi cables and to be honest i didn't see any difference between the two.
