Hi,

so I think my about 15 year old 920 setup is going to kick the bucket. I was going to wait for zen4 but it seems time is running out.

so I do three things on my computer
  1. occasional gaming. nothing fancy, witcher 3, counterstrike, but yeah i would like to give cyberpunk a go if i do get a new machine.
  2. lots and lots of boring word/excel stuff, usually with a few background things open
  3. data heavy, occasionally cpu heaving analysis

So i figure for the first one, a ryzn or intel standard setup with a decent graphics card is best, with emphasis on the graphics unit.
For the second one, i was thinking of getting a boxed low energy ready system. or just yet another docking station for my laptop. Focus is on keeping energy low. On the other hand, I do have 2 screens, one is 1920x1080 and the other is 2560x1440. also, i do want good sound to get out to play while i work, i sort of insist on an optical connector.
for the third, a threadripper setup would be best. i guess, 10ge is a must, so are ssds.

Since I am not going to buy 3 setups, i am going to ditch the threadripper. I think any up to date cpu is pretty good compared to my 920 intel, so that leaves a 10gbe connection as a must on the heavy load computer, which is sort of rare for the am4 it seems.

for the second one, i was thinking. one is probably not available and second is...well here we go what I was thinking:
1) I read that there might be way to turn the gpu off if not needed - since its going to be one of the biggest wattage eaters and even takes quite a bite in office mode. question: is that possible: amd comes with built in gpus, but is it possible to switch on the go? i read that there is a function where windows determines which program to run on which gpu, but how does that work connector wise? i mean the graphics card has its connectors and the in bulid gpu has its? so...you guys think this might work?

for number 2 i guess its just fiction:

2) is there any application to run two computers under one desktop enviroment and assign applications to different systems? i have never heard of such a thing, it would be like a mini cloud computer, consisting of just 2 "clouds", but i also have never heard of something that assigns programs to a "subcloud". While i do think this would be really really fancy and cool, its probably not existing or not practical. what i mean is this: i work on the small machine, then i decide to play along the working enviroment, so i start up the other engine, assign screen two and a game to it and go, keyboard and mouse shared. that is a bit one, i can only operate one set of input gadgets at a time, switiching for hardware reasons is exactly what i want to not do.

well i guess that would be the last option, to just operate two machines in parallel. but that is something i really dont want, i dont want two keyboards and two mice on my desktop or switches that i have to hit everytime i need to input the other system. or i just buy a regular computer and accept the electric bill as it is. but given that my computer is a main player on our energy bill...due to it running almost 12h a day it does warrant a thought or two to put into.

also i dont mind putting some money in it. i used to buy a decent mb and a lower end cpu, and upgraded ram etc along the way. as you can see i dont get a new system every other year but rather when it stops working. which seems to be the case now. not sure whats going on, but i have had so many glitches and problems i spend a considerable time fixing things which has to stop. recently i get start up errors evervy second time. i guess one of my ram sticks got busted. so: time for something new.

help appreciated.

Can you guys give me a recommendation for a mini pc? i looked at the amd driven brix from gigabyte, the video capabilities seem to cover my need for 2 screens well. but its a bit old for pci 3, but i wonder if it really matters. also amd has just confirmed to go zen2 on embedded processors. so i am willing to make compromises on this thing, but wattage should be low, and my two screens have to be supported, plus at least 1gbe. that is the minimum (1920x1080 and 2560x1440). i dont think the processor power matters that much, i guess everything today beats my intel 920.

looks really good. took me some time to find the wattage on this one but seems good. only downside seems to be that it has fans. how long did you have it? use it a lot?

I've had it since October.
Power consumption at idle is ~10 watt. Under load, I've not seen more than 28 watt.

Yes, it has fans. But silent except under extreme load.
I'm watching a movie on it right now. Sitting about 10 feet away...silent.
