Need vid card recommendation

Doesn`t matter if you`re not a gamer, you still want a good card.

Don`t even waste $125 on a video card, use the money towards memory.

Use the i7 6700 graphics for now, they get a 7.1 WEI score which is not too shabby at all.

What are your considerations for memory ?

your specs directly from manufacturer:
GIGABYTE - Motherboard - Socket 1151 - GA-Z170X-UD5 (rev. 1.0)

to give you an idea of how to figure this out for yourself {so you're not totally oblivious}

- check if motherboard supports onboard graphics. your does, and provides 1 dvi port {white}, 1 hdmi, and 1 displayport. That's pretty good, the only downside is if you need to use a vga {blue} connection to your monitor in which case you would need a dvi to vga adapter connected off the motherboard. your motherboard if purchased new may come with one.

- if using onboard graphics, make sure your cpu then supports onboard graphics. don't hold me to this but i believe all of the newest intel cpu's do i rarely see a consumer market intel i5 or i7 skylake that does not do onboard graphics. if this is your cpu: Intel Core i7-6700 8M Skylake Quad-Core 3.4 GHz LGA 1151 65W BX80662I76700 Desktop Processor Intel HD Graphics 530 - Newegg.com
then it supports up to a 4096x2034 monitor.

so if you are not gaming and need a run of the mill computer i would try the onboard graphics first before spending any money on a graphics card that you "probably" don't need.

but if you want a dedicated graphics card then you need to find one that is
- hardware compatible, check mobo specs, these days it's all pci-e x16 slot which you have... and it's an open slot you are not using it for something else.
- physically compatible, that will fit in your tower and not interfere with any other add-on cards you may be using
- compatible with power supply, that the power supply supplies the correct number if 6-pin or 8-pin supplemental power to the graphics card if it's a high end power hungry one, and that your power supply is large enough to support the card. anything less than 400w is usually a no go, and under 600w PSU you might be chancing it. if you put in a latest greatest power hungry card then worst case you can blow the PSU and wreck the motherboard, otherwise the system will be unstable and crash.
- check on videocardbenchmarks website for rating of cards that are best for the price, since you said no gaming no sense on buying something more than you don't need.
