PCI-E and VGA adapters

[MysterySlender]

When I connect a PCI-E 3.0 16x GPU to a PCI-E 2.0 16x MOBO does it affect the performance of the GPU? and the same question with DVI-I to VGA adapter?

PCI-E 3.0 is backwards compatible, which means it can connect with 2.0 and 1.0 and any other versions of PCI-E, and this comes with no performance loss. I believe the DVI-I to VGA adapter does not lose any performance, I have used something similar in previous years and didn't notice any sort of difference, maybe it could cause slightly lower quality, but overall its nothing major.

Hope I helped!

Have a great day,

No not really, PCI-e 2.0 x16 is still fast enough for all graphics cards.

DVI-I can output analogue signal (DVI-D cannot), so you should just use a DVI to VGA cable, not an adapter. These days you really should use DVI/HDMI/Displayport though as these are digital signals, so the picture quality is superior.

My monitor supports only VGA and max resolution is 1080p (1920x1080).
What is the diffrence between adapter and cable? why cable is better?

Adapters tend to slow down the communication (Not noticable) but a cable will allow instant and direct connections, and it will allow it communicate faster, and also allow it to be converted along the cable, rather than in a little adapter. This will also allow a better type of communication, keeping it fully analogue rather than converting to digital.

I would tend to go for cables over adapters, although I don't really see a difference, they're still both good!

An adapter will usually have a digital to analogue signal converter. A dvi-i to VGA cable will simply let the graphics card output the signal in analogue vga format.

I can't find a DVI-I to VGA cable (only adapter). Does it really matter?

I have used adapters in the past, and I haven't seen any really major, or noticeable difference, although the Analogue and Digital connections can cause some issues, it shouldn't be anything major to set yourself on a cable rather than an adapter.

Personally, there is no major performance loss, so there's nothing to worry about in my opinion.
