Hi, This is my first thread here so feel free to comment on my use of tag or categories
I’m currently building a new desktop PC (with obvious Ryzen 3 CPU and the potential AMD graphics card revealed soon or the Nvidia 30X0 cards with “decent” VRam models)
I’ve got a MSI X570 UNIFY with 3x (x16 PCIE) and 2x (x1 PCIE) slots
and will display either 1080p, 1440p up to 144Hz and 4K (144Hz when it can)
I intend to casually stream PC or console(even retro but not only emulation), but with my crap connection, won’t expect high resolution easily. However, I would like to be able to record with the best quality possible and with the highest framerate achievable for some analysis or thinkpiece videos.
I won’t try to compete with Digital Foundry though 
But I don’t know exactly what to expect from the capture cards limitation or from the onboard screen recording from Nvidia or AMD.
The recording will always have some impact but is recording + streaming an even higher demand on the GPU ?
The high-end GPU models will surely have enough power under the hood to deal with recording + displaying 144Hz at 1080p but will they be able to display a 144Hz 1440p or 60Hz+ 4K while recording themselves ?
Is a second entry model card used only for recording and encoding the output of the high end graphics card a mess to deal with or the constructors (Nvidia or AMD) came up with a proprietary solution ? (aka recording the output of the high-end card on an entry level of the same brand). Since the new cards will surely add the good codecs like h265 or AV1 / VP9, will there be a card that is the best in its price to deliver the classic GPU tasks with the bonus of good encoding ?
For recording external output from consoles (or retro with an adapter, yes PAL composite TIPS or recommendation are welcomed like the Open Source Scan Converter https://youtu.be/YCUrphpzEqY?t=925 ) I considered the staples like Elgato or Avermedia (in the gaming end) or some BlackMagick Design (video prod end) but would prefer an add-on card to my motherboard for a 1 box does everything approach. My desk have 2x 3U of rack 19" to fit some rack solution if it is the best suited for my need (and isn’t “too” expensive).
Does anybody :
-
know of incoming products (from Elgato or others) that deals with the 4K and up to 120-144Hz the new consoles are delivering to mass consumption and streamers with HDMI 2.1 and such ? In a desire to futureproof the rig, if you have any info
-
If there is some software caveats like OBS or X-split etc having limitation in their compatibilities,
To sum up I’ll list the products that seems to fit my needs and their prices and will edit with your recommendations or advices
