[SOLVED] Updated - need help in installing secondary graphic card

Hello all, I need your help to decide which graphic card suits my need.

Currently, I have a setup of 1 PC + 3 monitors. I’m using ASTER to create a virtual desktop to enable 2 users to simultaneously working on my PC.
Here is the setup

Graphic CardXFX HD 5770 1GB GDDR5
Monitor 1 (M1)Dell UltraSharp 24” Monitor: U2412M1920 x 1200 at 60 Hz
Monitor 2 (M2)Samsung SyncMaster P2350 23"1920 x 1080
Monitor 3 (M3)HP N270 27”1920 x 1080 at 60 Hz
Power SupplyCorsair 750W HX

Since graphic card can only generate output to 2 different display at a time, I link M1 and M2 using ATI Radeon Eyefinity.
So USER A will be using M1 and M2 (paired with Eyefinity), and USER B will be using M3.
But the problem with Eyefinity is that, it will force the lowest resolution of the paired monitor as the baseline, in which my M1 is force to use 1920 x 1080, which causes distortion in height.
I prefer M3 as a standalone monitor, since it has the largest dimension, so I can watch movies comfortably.

So, I’m planning to have a secondary graphic card, which does not need external power, since I don’t have any more power slots in my PSU.
I don't play games, only slight graphic processing, and mostly for coding, browsing and a little Youtube.

Can you guys give me any advice, or even better, any model that is compatible with my current setup?
An older version will do, preferably the one which use the same driver version as my current graphic card (to avoid conflicts in graphic driver).

So I have bought HD 5670 to be paired. After hardware and driver installation, my Windows 10 crashed on boot up, got BSOD.
Then I did several testing to determine what cause the crash.

Here are what I have tested

Monitors that connected to HD 5770 work fine

Is there anything I can do to make it works?

Thank you very much.

Good news guys. I managed to install both graphic cards, and the outputs are displayed properly to 3 monitors.

Here's how I did it:
  1. I removed HD 5670 from motherboard
  2. I uninstalled the graphic drivers for HD 5770 and HD 5670 using Guru3D.com DDU from SAFE MODE
  3. I reinstall HD 5670 to the motherboard
  4. Then I booted up Windows, let it reinstalled the drivers by itself
  5. I found out that HD 5670 is using proper graphic driver, which is AMD Radeon HD 5670.
  6. Meanwhile, for HD 5770, Windows installed AMD Radeon HD 5700 Series graphic driver, rather than my previous AMD Radeon HD 5570 driver.
  7. Not sure if that's the real solution, but it works for me
Thanks all.

The HD 5570, 5610 or 5670 are closest--they are essentially half of your HD 5770 so require no additional power. They each even support two analog monitors, something no newer AMD cards do.

Using exactly the same driver saves a lot of headaches--and in Windows 7 it is actually required. Note however the last ever WHQL driver for these was Catalyst 15.7.1, and the newer beta Crimson drivers break OpenCL and HDCP support

I see. I'm going to compare these 3 types then. Thank you for your suggestion.
