Hi,
I have my blood boiling too. For long time… and don’t know exactly why…
My system also nothing really fancy - 6 year Asus B85M-E with i7 4771, ssd system disk, some spare SSD and HDDs few USB devices used to be AMD Redon about 5 year old HD6450 just enough to offload graphics to two or three monitors. Have moved from Windows more than half a year ago maybe about year. Windows was just like a bee… use to use for photo editing and VMs and ordinary tasks… Started with 42.2 then reinstalled ones , then upgraded to 42.3 and from very beginning have something happening with the system… if I use VMware Wrokstation for some VMs then usually ending up to hot-reboot system because unusable. was blaming VMware. seems like form some updates was better, or hell knows… sometimes I use to live with… some times was just disaster. Usually after system wake up or there is something wrong with system, something maybe laging, or graphics seems not too responsive with simple window works or something, or after trying wake up there black screen with some errors related to GPU and frozen system… Sometimes after boot up and log in desktop un-responsible… Ctrl+Alt+Backspace couple times , log in again and if you lucky or not then again Ctrl+Alt+Backspace and then usually after second or third time you starting work. And then until some unknown time when something else will happen and then hell knows or rebooting or just keep trying to make some work with laggy system… Was blaming my GPU card so bought Nvidia Quadro 4000 not sure why, but because I heard people talking that for commercial systems so should be supported by SLES so… and Leap 15 become stable so reinstalled system from scratch with new card enabled nvidia repo installed, looks all good but not quite so good. some GPU performance test showing good results but simple desktop environment syysm not too sharp and doesnt look to responsive to any action. after system wake-up some distortions on desktop icons… and VMware Workstation released new version and from first look seems that it works, but eventually something still doesn’t work so fluently as suppose to. even VirtualBox not stable… have replaces from time to time maybe one or two mouses and dont know but seems that still it happening… seams that left button loosing a grip and releasing unexpectedly when dragging or even clicking so it seems that double clicking itself… SO I blamed maybe integrated USB hub in to monitor, or some other USB device even when I;m using USB CF card reader to downlaod photos from photo camera looks like I;m working with first single core 15 year old x836 computer, I have disconnected all USB devices so for first look it improved and I was nearly jumping form my chair up! but… seems that problem still exist . Somebody suggested to remove GPU and I did run system from integrated with CPU graphics. and there was something magical … Graphics just seem come alive QUICK and SHARP and SNAPPY and RESPONSIVE !!! I was shocked… all this time I have GPU to improve graphics but it doesn’t do anything, even opposite. And I thought I sorted all the mystic… but no… I;ve still got issue with mouse… I;m sometimes crying when nobody sees me… 
really sad… O yes . I have upgraded MB BIOS, so it improved a little bit on something but but not much… I was really thinking about to change distribution but only one thing what keeps me back is Yast. but probably like others they can live without so maybe I will survive?
I did open this forum just to look if any body else having such a problems… And I have only one answer to this - hardware incompatibility to this distribution…
Later on I will attache some screenshots and photos that I’ve done in time… But now its time to walk my dog…
This is General Chitchat. That means it allows you to talk about “boiling blood”. But it means also that I can stop reading the immense mass of characters without any paragraphs or other resting points that show the flow of arguments. Sorry.
And I have my eyes aching after trying to read that very long paragraph 
However, I think I got the gist. Your system works better with plain old integrated graphics and no fancy GPU. That’s been my experience, too.
… I’ll take your word for what the “gist” is, because my eyes glazed over at the very first look.
Your system works better with plain old integrated graphics and no fancy GPU. That’s been my experience, too.
Same here, my Intel onboard machines do just fine without any fancy GPUs. I cringe every time I see a “…with AMD” or “…with NVIDIA” problem.:X
Don’t want to get off-topic but will reply ones to such a reply to my msg.
Do are I’m talking with “hackers” that can’t read 20 line of text? :))) instead of reply in private with suggestion to put more effort text separation or whatever instead replying in line jut to confuse and help others to catch on same and go off-topic… No surprise that you have such amount of messages in your profile statistics.
I have difficulty to express my self in what situation I’m with my setup and how improperly it works, but will try to make a new post with a lot of paragraphs.
I am not sure what that is asking.
In any case, replies to your post are public. Anyone can read them. And I hope that answers whatever you were asking.
My Computer works well with Nvidia, it is almost a year that with openSuse Thumbleweed I have no problem, it is also true that I have a simple system, a single monitor and I use little Virtualbox
The last 5 lines or so seem to describe your “discovery” that your original hardware performs better than what you did to try to improve.
That’s not necessarily a unique result.
All a person can do is research as best as possible before actually trying things out.
If you’re trying to push the limits of anything,
I’d recommend you first collect as much information as possible and in particular specific documentation and guides with a higher priority on very recent articles, then do your best.
You’ll find I’ve offered similar advice on a number of Forum topics when the @OP is asking about something that is on the bleeding edge.

Forum “be nice to the originator” service:
My view of the issue at hand:
- CPU is an Intel – 4 core i7 Haswell …
- The system has 3 monitors of unknown resolution …
- The system is used for processing photographs – no mention of colour calibration with respect to the displays …
- The AMD 6850 had two DVI, one HDMI, and two Mini DisplayPort ports – no mention of how the displays were connected to the Graphics unit but, there is a mention of a USB hub …
- The Nvidia Quadro 4000 is professional CAD graphic unit with a dual-link DVI port and two DisplayPort ports – ditto display connections …
- There’s no mention of which Desktop GUI is being used to handle the multiple monitor situation …
- There’s no mention of how the BIOS was setup to handle the situation of the CPU’s GPU and the graphics card in a mainboard slot …
- There seems to be need a need for the system to support Virtual Machines.
- There’s no mention of the expectations with respect to how the Virtual Machines should be handling the multiple displays …
- There seems to be a USB data throughput issue – yes, extracting 12 MB JPEG files from a camera’s SD 95 MB/s card via USB-2.0 takes a minute or two – USB-3.x is faster …
My view is that, we need some detail, at least for some of the points I’ve listed above.
As this is in General Chitchat and not in a serious technical help forum, I strongly suggest that when the OP want to follow this advice, to do so in one of the technical help forums. It might then draw the attention of people that are using the forums to help other users with technical problems.
Indeed. The opening post was moved to chit-chat from a technical help forum (tacked on to an existing thread) precisely because it was not a request for help (also lacking the technical information required), and the OP was invited to start a new thread in a technical help forum if/when they decided they wanted such assistance.
It seems that, in the digital photography world, there’s a trend to using multiple displays when editing the pictures – image editing or image processing …
It seems that, often the image being edited is displayed on a calibrated high resolution wide gamut monitor and, the other monitors are used for the various tool boxes of the application being used for picture editing …
In photography related forums, there are questions being asked around the issue of performing colour calibration on multiple displays …
[HR][/HR]So, maybe if the originator of this thread could, maybe, provide a little bit more information about the wished for work environment, maybe, we could point to advice on setting up high performance multiple display systems …
