Interesting response. The monitor is:

Per its manual, the max/native resolution of that monitor is 2560x1440,
so a video card that exceeds that spec won't give you any better
display. DVI will support well that monitor at a refresh of 60Hz.

Although the general spec says vertical refresh is 55 to 75 Hz, you're
probably limited to 60 Hz at the max/native resolution. From its
manual, page 26:

Support max. resolution
DVI: 2560x1440 @ 60Hz
HDMI: 2560x1440 @ 60Hz
DP: 2560x1140 @ 70Hz

Going to a DP connection gives you all of another 10Hz in refresh rate
which is neglible even in video games. Unless you get a video card that
hits that resolution, or higher, and at much higher refresh rates, like
144Hz, buying a new video card will give you nothing more than your
current monitor can already use with your existing video card.

The video card is:

The site never mentions refresh rate at which resolutions. I downloaded
the video card's manual. Says "Supports resolutions up to 2560x1440".
The video card supports the monitor's max/native resolution, but no
mention of refresh rate. I'm guessing its 60Hz at 2560x1440.

Getting a higher resolution video card with a DP port won't magically
make the monitor increase its resolution or refresh rates. In addition
to buying a better video card to get a DP port that supports higher
resolutions along with higher refresh rates, you would need to get a
better monitor (higher resolution, plus higher refresh rates).

Your video already supports the max/native resolution of your monitor
using a DVI connection. All a new video card with DP will give you is
possibly another 10Hz in refresh rate (provided the monitor has an INF
driver file you can install that specifies the higher refresh rate).
You'd be wasting your money buying a new video card unless you also get
a better monitor (higher refresh rate; e.g., 144Hz).

What you have is a passively cooled video card. No fan for active
cooling. That means the video card hopefully throttles its GPU cycles
to keep heat below some maximum threshold. While not having a fan means
the video card is quieter, you can get newer and more robust video cards
with fans for active cooling that are very quiet. In my new build that
has twice as many fans, it is far quieter than my old build. I have to
look at the lights (Power, fans) to know it is powered on. Once in a
blue moon I've loaded the GPU so hard that its fan had to speed up, and
that was not during video gaming. Active cooling means you could extend
the temperature range of the video card. Well, not let the temperature
get higher but incur a higher load on its GPU without exceeding the max
temperature. Newer games would hit the GPU harder; however, yours has a
reduced number of shaders, so you might be restricted what video games
you can play or they have to use less shaders meaning less load meaning
less heat.

I half suspected that there'd be nothing in it for me to change to DP
so thanks for confirming it.
