About DVI's... someone tell me if I got this right.

The point of all this, is because I just got a new (budget) video card (GTX 650 Ti) and I did some research since it has a dual link DVI-I and DVI-D ports and a mini-HDMI port. I understand dual links to be better than single links, but I didn't really get the difference between DVI-I and D. So... in a nutshell...

Single link = Upto 1920x1080 screen resolutions.
Dual link = Greater resolutions.

DVI-I = Works for both analog and digital signals.
DVI-D = Digital signals only.

Which means to say that on a DVI port, using a DVI-I cable and a DVI-D cable makes no difference. As long as the pins fit, either is fine. DVI-I is just more versatile. And if your monitor has a native resolution of 1920x1080, then using a single or dual link DVI-I/D cable makes no difference. It would make a difference if you had, say, a 2560x1440 or generally anything bigger than 1920x1080.

And since HDMI is basically a single link DVI, whether I use (my current) DVI-I single link cable, or a (mini) HDMI cable, it also makes no difference.

Does this sound about right?

Pretty much

DVI-D = Digital only (missing 4 analog pins)
DVI-I = Analog+digital
DVI-A (rare) analog only

Not that a DVI-A or DVI-I cable may not plug into a DVI-D only port depends on if it has the extra holes or not

Single link dvi you will also be restricted to 60hz along with hdmi to 60hz as well. Dual link dvi allows the higher resolutions like you said and higher than 60hz.

DVI-I can also take a DVI to VGA adapter. DVI-D cannot be used with an analog adapter, but it can be adapted to HDMI.
