There's probably NO advantage for your monitor. In your case, DP and DVI would likely be EXACTLY the same.
*If there WAS an advantage, it would be with DP likely and since otherwise DVI is identical I can't think of a reason to use DVI over DP.
Input lag has more to do with the SCALER and Video Processor (if any) inside the monitor though I suppose the DP signal may be more efficient and thus decode faster. The reason why many HDTV's have a "GAME" option for HDMI inputs as it disable the video processor to minimize input lag.
For scaling, I actually set my Video Control Panel so that scaling is done right on the video card itself:
a) Scale on GPU
b) Scale by Aspect
Or similar names. I have my monitor settings (on the monitor itself) so it does not scale (1:1). What happens then is if I game at say, 1600x1200 my video card scales this properly and outputs a 2560x1440 signal at all times (or whatever your monitor max ratio is), thus no scaling need be done on the monitor itself.
A modern video card should be faster at scaling than all/most monitors.
Summary:
- DP vs DVI probably makes little difference (especially if already scaling on video card)
- recommend scaling on video card

DP is always good. But so long as it doesn't matter either way then I'd use DP. It would leave the DVI port open for something like a console. Of course if you don't own a console then it doesn't matter.
