A 2K monitor is not that expensive but then you need a beefy GPU and PSU and better case capable of removing all that heat and a bigger table and a bigger room and a better processor and more RAM and more blinking lights and... Alright, I am exaggerating a bit.

If we are talking strange graphics cards so there are on the market some mining cards that have NO ports whatsoever but cost a fraction of what the equivalent GPUs cost. I wonder what a normal person could use them for. If Nvidia card maybe use one for PhysX? Could you make the picture with them then plug in one of those USB 3.x to DP adapters? and get the picture out that way?

Maybe you could pair it up with a card with normal video output (HDMI, display port, etc.) and have an SLI/Crossfire rig?

Those I spotted all had only 4GB of VRAM but maybe in SLI/X-F you only use one card's VRAM, I think.

1080P = 2K

2K refers to the amount of horizontal pixel, and 1920 is around 2000 pixels = 2K.

I believe windows 10 let you process the graphics with Pci-e GPU and send picture with integrated GPU. There is a setting used to laptops dual grapics and some desktops with dual graphics as well (yes there is some, for exemple the HP Pavillion 550 with this card).
Its a pain in the arse to setup, as usual windows10 auto updates borkes the driver and resets every thing (yes, even on OEM machines) but it works. Probably doable on Linux as well but well beyond my knowledge.
There are a couple of sites talking about this feature where you could enable G-sync with AMD GPU (and vice versa) well before Nvidia finally open up G-sync. If I remember that Linus guy talked about that.

Last year on black friday, there were a lot of mining GPU's on sale, I almos bought a couple of Rx570 for 75€ and Rx580 for 95/100€ both with DVI output only.

Sorry, I should have clarified. By "1080" I mean 1920 x 1080. This chart shows that 1920 x 1080 is a different resolution than 2k.

I have no idea why anything lower than 1920 horizontal pixels is called 2K, but it does show that 1080P (=1920x1080) is the highest 2K resolution.

2K is only mentioned among broadcast resolutions... but 1920x1200 is 2K too. I guess the writers don't care/know too much about computer technology.

Ooooops! See, even I know so much about computers still learn something new most weeks, I meant 2560x1440 (WQHD).

Sadly I spotted no mininig cards with any graphics ports for sale or I would have probably jumped on it.

Sometimes called 2,5K ;-)
And about your original question. Usually the more expensive versions of each model have better cooling and are quieter. I have good experiences with MSI Gaming and Gigabyte Windforce cards.

I guess it depends on what case you install it in... I have a Fractal Design Define R5, which is a really cool and quiet case (and relatively big). So I guess I could go for a louder hotter card. (but I don't want to, I have time to await better future deals)

I guess most of those who bought the GPU that this thread started about are just suffering the noise and using headphones to keep it out. 35-40% lower price than models with good cooling is A LOT cheaper. Funny how I did not think of how headphones and walls with good sound proofing/insulation or no neighbours would make the GPU a good choice. Two things I do not have myself. Poor fans will have to work at full speed all the time though.

5700 went as low as £250 (after cashback) but a 580 will run nearly everything at Ultra at 1080p 60hz bar hogs like Kingdom Come Deliverence, Metro Exodus and Red Dead 2

If your system is a few years old it maybe your CPU will bottleneck the GPU anyway

Also something to remember is I believe modifying the card would void the waranty

PC built in October :-)

I did not want to buy a GPU from too far away in case there are guarantee issues. Here the AMD 5700s did not go down at all during the weekend. Cheapest was 20% higher (includes correction for different VAT rates and exchange rate for the weekend.)

Modifying the cooler in any way will most certainly void the guarantee instantly.

What CPU did you use? Hopefully not the 4 core 4 thread 2200g I used as the lack of threads bottlenecks many modern games.

Six cores, twelve threads Ryzen 3600X. Sure I wanted eight cores but it was expensive as it was already. Also, the 3600X is two generations newer technology than the 2200G.
