I still have some old graphics cards in my pocket and would use my desktop as a general-purpose PC so for games, video streams etc and to power a small graphics card to the big built-in so 20W but I have those graphics cards no programs As with laptop assign there's still a metode to make my my hiredware and all the other devices that I have the use I have for something
My PC:
I7 7700 floor
16GB ram
HDD1TB 2 times
GTX 1060 6GB
All graphics cards I could use:
GT 710 1GB 19W
GT 635 2GB watts?
AMD 6570 1GB watts?
AMD 5450 1GB 19W has problems the PC does not recognize the card
GT520 or 620 are both names on it
To save energy you need to install no graphics card. That would only consume additional power and otherwise your processor already has an integrated, which is quite economical. So leave the PC as it is.
Does not make sense, you always have to change the monitor. And it would probably save energy to use the IGPU instead of another card.
The internal one is disabled but I also do not know how I can make the switch as on the laptop auserdem goes the IGPU on the CPU so the CPU is charged more heavily
Yes, but the internal graphics card does not need the ram of the CPU an external gpu
And where does that limit you? 16 Gb Ram are enough for office and multimedia
Not at all, because you have to change the cable. Can connect the monitor to both with different cables and then change the input in the menu of the monitor. Or you let it be easy, bring nothing anyway. Low power consumption you probably want to have in desktop mode, right? Since the GTX 1060 does not need 15W more.
Yes all desktop work is streaming games all this
If the games use more than 16GB ram one has to max 20 to 30GB needs
This is futuristic and meaningless, since your IGPU then anyway not enough for it
So much: all of your listed graphics cards are significantly slower than the internal ones of your processor (check gpu.userbenchmark.com if you want to compare things in the future).
So, the 1060 at idle wants to have a power draw of 9W (https://www.tomshardware.com/reviews/nvidia-geforce-gtx-1060-pascal,4679-6.html)
So either way just leaving it is is your best choice. I don't know if you can do anything like nvidia optimus (switch between igpu and 1060 dynamically) but there sure is a way.
Just leave it as it is
Yes, as I said, it just stays with the 1060, which consumes pretty little at idle. With any other card you would only increase the consumption.
English text does not bring much with me because I can't speak English
Sorry.
So summarized: your 1060 on Idle is more economical than the 20Watt you mentioned (9W in idle loud https://www.tomshardware.com/reviews/nvidia-geforce-gtx-1060-pascal,4679-6.html)
Also, the internal gpu of your processor is much faster than all you have listed (gpu.userbenchmark.com).
So it just makes sense to leave everything as it is. Of course, it makes sense to see if you can find a way to dynamically change your graphics card usage between the igp and the 1060, but installing the other graphics cards has only disadvantages.
