So i have an amd r7 250 currently running. I just bought another monitor and i cant connect it to my amd.I want to have 2 monitors running. I have an old ati radeon x550 to which i can connect my other monitor. Is it possible to use both gpus and monitors at once ?

In the old days I used 2 cards but not as you described. It "was" possible to install an ATI card and an Nvidia card and use the ATI card as your GPU while gaining the benefits of Nvidia's proprietary technology like PhysX. Unfortunately Nvidia put a stop to that. As far as I know, in order to use 2 GPU's, you need to SLI or Cross Fire them and they have to be chips of the same architecture. In other words, you need a 2nd r7 250.

I wrote my question like a dumbass. I want to have 2 monitors running and having like an extended desktop so i can play games on one monitor and have my desktop or chrome open on the other monitor without crossfire.
 

If you don't run them in crossfire then I believe this is possible, I know it is with NVIDIA if you turn off SLI.

1 - you can run as many graphics cards as you want, all different or all the same, whatever can physically fit
2 - you can mix AMD and Nvidia as long as they're running separate monitors
3 - why can you not run two screens from the R7-250 card? nearly every card made in the last 10 years can run 2 displays without a problem
4 - does your motherboard have onboard graphics? you can use that in conjunction with the R7 card
5 - ignore gamers who don't have a clue and always assume that you absolutely must SLI / CrossFire stuff, as if that's a law or some such BS
6 - experiment! it's the best way to learn. if something breaks, you have backups, and a restore point! you DO have backups, right? and you DO use restore points, right?

I did experiment and i had no success. When i put the ati x550 gpu in my pc i had to install the drivers. I found out how to install them. But when i installed the drivers for the x550 the r7 drivers uninstalled or something and i was left with x550 running only. I could use 2 monitors with the x550 but then i couldnt play my games cause the r7 wouldnt be running. But when i tried to install r7 drivers the x550 drivers dissapeared and the r7 would be the only one running. I cant connect the monitors to r7 cause the monitors have only vga inputs and i dont have the adapter needed for a second monitor. The r7 has a vga output, hdmi and dvi-d output. And sorry for the late response.

Like I said, typically has to do with drivers. I would run Nvidia and ATI cards together until they began "sabotaging" the drivers.
I even had a motherboard that had an Nvidia Ethernet adapter and as soon as I installed an ATI card everything stopped working.
You can see if you can manually extract the drivers to different locations, then go into your device manager and point the cards to the correct drivers.
