VisionTek AMD Radeon RX 580 8GB GDDR5 Single Slot Video Graphics Card for PC 256-Bit DirectX 12, 75W Bus Power, PCI Express X16 3.0, 6 mini DisplayPort

"Neo, the Matrix has you"...This definitively helped rescue Neo from the Matrix. This is a low power card that was easy to install. It is nice and slim, taking up only one slot even with the heat sync so there was plenty of room for the other hardware required to jack in to the Matrix. The card powers 6 monitors flawlessly had high quality 4k to keep an eye on the green rain that is the Matrix. The card did not have any problems running off of a 250W PSU nor a 500W PSU. Still works without issues in Windows 11. May have to manually install the drivers though.

I was previously using dual AMD Fire pros. During the hurricane lost my other system and had to put something together on a budget. I was able to source a refurbished system that had the processor and memory I was looking for, but only an onboard video option. In my profession, I am constantly remotely connecting to other systems and like the ability of spreading the tasks across multiple monitors.This card is of only a few I found at this price point that would support more than four displays. Most of the other options contain mixed video interfaces. I like the fact that this card has six mini display ports with a thumb screw option. It keeps everything nice and tight and the stress off of the smaller connectors. I was concerned that the overall memory of the card would not be enough to satisfy my needs however, I have been quite impressed with its abilities so far.I currently utilize four of the monitors in a working sense while the other two are dedicated to my Email client and video surveillance. Anyone who has ever used an email client knows what memory hogs they are, but are nothing compared to surveillance displays. This card chugs right along and is able to open additional task windows from various programs simultaneously across the four working screens and a quick and snappy manner. They are significantly faster than my previous set up which combined carried six times more total memory (12).I have been highly impressed with this card for production and monitoring of tasks. This is not for gaming by any means but more of a workstation card. If you are on the fence about purchasing this, I hope my experience helps lead to your final decision

I actually got 2 of these cards after I found a lot of cheap 15" LCD monitors and a few multi-monitor mounts to complete my ridiculous office computer system. I don't really do a lot of heavy gaming but you should see how many news channels I can watch at once while most of them lie to me about whats going on in the world and now I take having too many browser tabs open to an unholy level. ;)I'm not sure why I haven't seen any improvement whatsoever from using the CrossFire jumper ribbon in all my tests I've done, but I've tried everything just to get all the monitors to work properly in the first place (also after an ABSURD investment in mini-DisplayPort adapter cables).The cards work ok, but getting all 6 monitors to work off a single card has been PAINSTAKING. I'll try to include a few of the most important details of my expensive and tedious (albeit SUCCESSFUL) venture in getting over 9 monitors to work off of one single system (my previous record was 8, using 3 display adapters)Pro Tip:I finally decided to just go with "straight cables" that are mini-DP on one end, and a mix of VGA, DVI and HDMI for the other end which match whatever my monitors have. This kept me from constantly ordering, testing and returning all the gizmos and doodads that are "PASSIVE" and not "ACTIVE", since a lot of sellers seem to deliberately leave out whether the adapter devices they sell are PASSIVE or ACTIVE.For a single card setup:I noticed that I could not put 6 "digital" outputs on a single card, nor could I put 6 "analog" outputs on a single card.This basically means that if you want to get ALL 6 displays to work on a single card, 2 of them needed to be "analog", which (for ME anyway) means VGA inputs are needed on at least 2 monitors. I got lucky and had a few monitors I picked up in the lot that had both VGA & DVI inputs (Note: I don't have a DP input for any of my monitors, but it might was in "analog mode". Maybe. YMVV.) but I also have a large HDMI monitor I use for "presentation" of videos and such (A super old and heavy Plasma TV). After experimenting with different configurations of which ports connected to which monitors worked or didn't work, I was FINALLY able to get all 6 monitors working on a single card.I was as scientific as possible in my experimenting of how to get it all working and debug my issues, but it wasn't a fully equipped computer lab. I had a bunch of leftover cables and connectors I'd acquired over the years but I didn't have any mini-DP cables, so I used some of the little adapters that came with the card to test out certain configurations with my limited count of VGA-to-VGA, DVI-to-DVI, DVI-to-VGA adapters & cables, and DVI to HDMI adapters & cables... I used to be "that computer guy" that people ask for odd cables and the like from, but now I just keep it all in 2 storage bins in a closet. I'm more equipped than most people in this regard, but I don't have it all. Maybe having a mix with more DisplayPort monitors would work fine too, but those tend to be pricey and you won't find a cheap lot of them used anytime soon. I apparently spent all the money on cables and bargain bin monitors.RECOMMENDATION For 2 of these cards together (7+ monitors):For my experience, I noticed that installing one card at a time is the way to go. DO NOT try to just install 2 cards and hook up every monitor to them, flip the switch and hope Windows will take care of it all for you! It will not... After about 10 total hours of FIGHTING with it in various ways, losing some use of monitors and trying to fiddle with settings and drivers to get them all back, only to lose other monitors when I regained the ones I originally lost... (super frustrating), I finally unhooked EVERYTHING, and started from scratch. I also too the time to LABEL my wires on BOTH ends so that I could figure out which ones work on which devices. It has made moving around the computer FAR easier as I don't have to play with settings and use process of elimination every time I move my desk. I HAD to un-seat one of the 2 of these cards I have everything Windows would automatically update the device driver. I would come home from work to find that half my monitors weren't working and try to figure out what the deal was... it was almost always because of a driver update.Eventually, I got Windows to recognize all 12 monitors on 2 of these cards too by "cheating" and plugging the monitors with more than 1 or 2 input types up to the 2 different cards to "trick" it into thinking I had more monitors than I actually did. This was a neat trick that only worked on some monitors, not others, but it helped me figure out whether I needed to try a new connector / wire / adapter / whatever if I wanted to add more monitors and cap out my walls with all the video the computer is capable of handling (muahahaha!)NOTE: The last 2 driver updates that Windows 10 performed automatically have actually gone swimmingly and I didn't have to touch a thing. THANK YOU TO THE DRIVER DEVELOPERS FOR WORKING THAT OUT!In summary, expect to have to test test test test test test test and TEST some more, LOTS of trial and error, maybe a few times ordering the wrong cables or getting a bunk "PASSIVE" adapter instead of the "ACTIVE" adapters that WORK for us with more than 2 monitors... lots of cussing... and if you don't have a labeling system for your ports on the back of the video card AND on the connector wire end plugging into it AND on the connection end of the wire/cable AND the monitor that its connecting to, YOU WILL have a BAD TIME if you try to move your desk and plug everything back in.
