Help required with mixing integrated graphics and graphics card

Invicta · 9 Apr 2023 at 09:13

I am looking to build a new PC as my current one is so old it struggles with 4K video editing. My thoughts are:

ASUS Intel Z790 ProArt motherboard
Intel i9 13900K processor
ASUS Nvidia Geforce RTX 4080 16GB graphics card

My queries are about the Intel i9 13900K graphics. This is a recommended processor for 4K video editing, so first question why would the integrated grahics version be recommended over the same processor without integrated grahics, can I save a little cash? My main query is how do I connect my two monitors? Do I plug them into the graphics card or the I/O panel HDMI port on the motherboard? There is only one HDMI out on the motherboard I/O board so that would be a challenge for two monitors. Can I just plug the monitors into the graphics card? The monitors are old so do not have thunderbolt support.

Some software uses the integrated graphics to accelerate too. Worth checking with the software you use.

Both monitors should be plugged into the graphics card.

I would always go with the integrated graphics CPU as it is really useful when troubleshooting issues - helps separate graphics card issues from general hardware ones.

Also useful if you're between graphics cards, or testing them, or you're doing a quick test build before selling parts etc.

As above, plug displays into the graphics card.

Many thanks for the replies I think I will stay with the i9 13900K version. I use Davinci Resolve for video editing, from what I can find out it is recommended to turn off auto select for GPU and select Nvidia for the dedicated graphics card. Sounds like Davinci only uses one or the other.

A few years back I had two Nvidia graphics cards in my PC build, but had lots of issues with Windows updates failing as the Windows updates were not tested with dual card setups. I the end I got a new, single card with dual outputs. Anybody know if Windows updates have issues when you have a mixture of integrated and dedicated graphics?

It's very unlikely given the sheer number of people running a setup like this

I suspect the issue before was related to one driver for two Nvidia devices, whereas the Intel graphics will have their own driver.

This is a pretty expensive board, do you need all the features?

A few of the features:
- 10Gb ethernet
- 2x ethernet ports (one is 2.5Gb)
- 2x rear I/O, USB Type-C rear Thunderbolt ports
- 1x front, USB 3.2 Gen 2 USB Type-C 60 watt PD
- 2x PCIE 5.0 full length slots (runs in 8/8 mode)
- 4 M.2 ports
- 8 SATA ports

Thanks for the Youtube link, that guy really likes the integrated graphics. I think the Adobe products must be better at using the IGPU than DaVinci Resolve. All the info I can find suggests Davinci only uses one or the other depending what you set in the config parameters.

Do I need all the features on the Motherboard - not all of them but I do want to use

Three out of the four M.2 ports, seven of the SATA ports and Thunder bolt port for external storage. Using those SATA ports for internal hard drives raises another build issue, can I get the both the drives and graphics card in the case? The card is 348.2 x 150 x 72.6 mm. I was looking at a Fractal Design 7 (I am used to Fractal Design on my other builds), without drives but with fans it has room for 467mmm. Question is can I get six hard drives and an optical drive in the top half of the case leaving me room at the bottom for the graphics card. Does anybody have such a build?
